Logarithmic formulation​

Answer»

Step-by-step explanation:

  • Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base B if bx = n, in which case one writes x = logb n. For EXAMPLE, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.

An army contingent of 616 member is to march behind an army bound of 32 member in parade .The two groups are to march in the same number of columns . What is the maximum number of columns in which they lan march?​

Answer»

Answer:

answer is below my questioner.

Step-by-step explanation:

HCF (616,32) is the maximum number of columns in which they can march.

Step 1: First find which integer is larger.

616>32

Step 2: Then apply the Euclid's division algorithm to 616 and 32 to obtain

616=32×19+8

Repeat the above step until you will get remainder as ZERO.

Step 3: Now consider the divisor 32 and the remainder 8, and apply the division lemma to get

32=8×4+0

Since the remainder is zero, we cannot PROCEED further.

Step 4: Hence the divisor at the LAST PROCESS is 8

So, the H.C.F. of 616 and 32 is 8.

Therefore, 8 is the maximum number of columns in which they can march.

How many digits will be in the square root of the 28digit number?​

Answer»

ANSWER:

Do you know that the sum of the first five prime numbers, i.e., 2, 3, 5, 7, and 11, is 28? Another interesting fact about 28 is that it is a perfect number because the sum of all the numbers that divide 28 perfectly is 28. 1+2+4+7+14 = 28. Isn't that interesting? The number 28 is ALSO a triangular number. It means the number of dots in SEVEN rows of triangular dots is 28. In this chapter, we will calculate the SQUARE root of 28 by long division method along with solved examples and interactive questions.

Let us see what the square root of 28 is.

In an arthmetic progressive the sum of the three terms is 24, and their product is 480, write three terms os the arthmetic progression?​

Answer»

Step-by-step explanation:

SUPPOSE the THREE terms be " a - b, a, a + b "

SUM = 24                  

a-b+a+a+b=24

3a=24

∴a=8

Product = 480

(a−b)(a)(a+b)=480

(8−b)(8)(8+b)=480 {( we know a=8)}

(8−b)(8+b)=60 {we know (a-b)(a+d)=a^2-b^2}

64−b^2=60

b^2=4

b=2

 a=8,b=2 

a−b=8−2=6,

a=8,

a+d=8+2=10

terms are 6,8,10.

Answer»

Given : company ADVERTISES Make Fixed Deposits of 50 lakhs with us

become crorepati in 5 years flat!

the company offers simple interest.  

To Find : rate of  interest    

a) 15%

b) 20%

c) 255

d) 25%​

Solution:

Make Fixed Deposits of 50 lakhs

=> P =  50 lakhs

become crorepati

=> A = 100 lakhs  ( as  1 crore = 100 lakhs)

R = ?

T = 5

SI = P * R * T /100

A = P + SI

=> 100  lakhs = 50 lakhs + SI

=> SI = 50 lakhs

SI = P * R * T /100

50 lakhs  = (50 lakhs ) * R *  5 / 100

=> 1 = R/20

=> R = 20

Rate of interest is 20 %

Show that, 7 log⁡〖(10/9〗)+2 log⁡〖(81/80〗)=2 log⁡〖(25/24〗)+log⁡2

Answer»

Step-by-step explanation:

Given:-

7 log (10/9) + 3 log (81/80)

To find:-

SHOW that:-

7log(10/9)+3log(81/80)=2log(25/24)+log 2

Solution:-

LHS:-

7 log (10/9) + 3 log (81/80)

We know that

log (a/b) = log a - log b

=> 7(log 10 - log 9 ) + 3( log 81- log 80)

=>7 log 10 - 7 log 9 + 3 log 81 - 3 log 80

=> 7 log (2×5) - 7 log 3^2 + 3 log 3^4

- 3 log (2^4×5)

We know that log (ab) = log a + log b

=>7 log 2+ 7 log 5 -7 log 3^2+3 log 3^4

-3 log 2^4+ 3 log 5

We know that

log a^m = m log a

=>7 log 2 + 7 log 5 -(2×7) log 3 +

(3×4) LOG3 -(3×4) log 2 + 3 log 5

=> 7 log 2 + 7 log 5 -14 log 3 + 12 log 3

-12 log 2 -3 log 5

=> (7-3) log 5 +(-14+12) log 3+(7-12 ) log 2

=> 4 log 5 -2 log 3 -5 log 2 -------------(1)

RHS:-

2 log (25/24) + log 2

We know that

log (a/b) = log a - log b

=> 2 log 25 - 2 log 24 + log 2

=> 2 log 5^2 - 2 log (2^3 ×3) + log 2

We know that

log (ab) = log a + log b

=> 2 log 5^2 - 2 log 2^3 - 2 log 3+ log 2

We know that

log a^m = m log a

=> (2×2) log 5 -(2×3) log 2 - 2 log 3 + log 2

=> 4 log 5 -6 log 2 - 2 log 3 + log 2

=> 4 log 5 -5 log 2 -2 log 3

=> 4 log 5 - 2 log 3 - 5 log 2 --------------(2)

From (1) &(2)

LHS = RHS

Answer:-

7log(10/9)+3log(81/80)=2log(25/24)+log2

Used formulae:-

  • log (a/b) = log a - log b

  • log (ab) = log a + log b

  • log a^m = m log a
