Simplify(i)(2)^2/3×(2)^1/5(ii)(7)^1/5(iii)(32)^2/5(iv)(125)^1/5

Answer»

ANSWER:

Step-by-step explanation:

Hi ,

write 81 ,216 , 32 ,225 as product of the prime.

1 ) 81 = 3 × 3 × 3 × 3

2 ) 216 = 2 × 2 × 2 × 3 × 3 × 3

3 ) 32 = 2 × 2 × 2 × 2 × 2

4 ) 225 = 3 × 3 × 5 × 5

Now ,

i ) fourth root of 81 = ( 81 ) 1/4 = ( 3^4 ) 1/4 = 3 ^ (4 × 1/4 ) = 3

ii) ∛216 = ( 216 ) 1/3 = ( 2³ × 3³ )^ 1/3 = [ ( 2 × 3 )³ ]^ 1/3 = (2 × 3 ) = 6

iii ) fifth root 0f 32 = ( 32 )^1/5 = ( 2^5 ) ^1/5 = 2

IV ) √225 = √ ( 3 × 3 ) × ( 5 × 5 ) = 3 × 5 = 15

Given problem is ,

fourth root of 81 - 8 ∛216 + 15 fifth root of 32 + √225

= 3 - ( 8 × 6 ) + ( 15 × 2 ) + 15 [ put from ( i ) to ( iv ) values ]

= 3 - 48 + 30 +15

= 48 - 48

= 0

hope it helps

:)

Please so it I will mark you as brainliest

Answer»

Answer:

AMOUNT = 45254, CI = 11254

Step-by-step explanation:

P = 34000, Time = 3 years, R = 10%

A = P(1 + r/100)^N

= 34000(1 + 10/100)³

= 34000(110/100)³

= 45254

C.I = A - P

= 45254 - 34000

= 11254

18.	Which one of the following is ax3- 19x + 30 ?
Answer» Step-by-step explanation: Given, F(x)= x3 – 19X – 30 In f(x) putting x=±1, ±2, ±3, we see for which value of x, f(x)=0 f(−2)=(−2)3−19.(−2)+30=0 We observe that f(−2) = 0 From factor THEOREM, we can SAY, (x+2) is a factor of f(x) x3 – 19x – 30 = x3 – 19x – 30 = x3+2x2−2x2−4x−15x −30 = x2(x+2)−2x(x+2)−15(x+2) = (x+2)(x2−2x−15) = (x+2)(x2−5x+3x−15) = (x+2)( x(x−5) + 3(x−5) ) = (x+2)(x−5)(x+3)

18.

Which one of the following is ax3- 19x + 30 ?

Answer»

Step-by-step explanation:

Given, F(x)= x3 – 19X – 30

In f(x) putting x=±1, ±2, ±3, we see for which value of x, f(x)=0

f(−2)=(−2)3−19.(−2)+30=0

We observe that f(−2) = 0

From factor THEOREM, we can SAY, (x+2) is a factor of f(x)

x3 – 19x – 30 = x3 – 19x – 30

= x3+2x2−2x2−4x−15x −30

= x2(x+2)−2x(x+2)−15(x+2)

= (x+2)(x2−2x−15)

= (x+2)(x2−5x+3x−15)

= (x+2)( x(x−5) + 3(x−5) )

= (x+2)(x−5)(x+3)

How to solve question no. 5please fast

Answer»

GIVEN:-

$\rm{4\sqrt{3} + ( 4 + \sqrt{3})(4 - 2\sqrt{3})}$

TO FIND:-

It is a Rational NUMBER or irrational Number.

HOW TO SOLVE?

First we will Simplify the sum which is in bracket.

After Simplifying bracket, we can simple Operations to get the value.

After that we will INSPECT whether it is rational or irrational.

Now,

$\implies\rm{4\sqrt{3} + ( 4 + \sqrt{3})(4 - 2\sqrt{3}}$

$\implies\rm{ 4\sqrt{3} + (16 - 8\sqrt{3} + 4\sqrt{3} - 6)}$

$\implies\rm{ 4\sqrt{3} + 10 - 4\sqrt{3}}$

$\implies\rm{\cancel{4\sqrt{3}} + 10 -\cancel{4\sqrt{3}}}$ .

$\implies\rm{ 10 }$

Hence, The value is 10 and it is a Rational number.

47.	3/4+11/2=7/12+a solve
Answer» $\frac{3}{4} + \frac{11}{2} = \frac{7}{12} + a$ $\frac{(3 + 22)}{4} = \frac{7}{12} + a$ $\frac{25}{4} = \frac{7}{12} + a$ $a = \frac{25}{4} - \frac{7}{12}$ $a = \frac{75 - 28}{12}$ $a = \frac{47}{12}$ Therefore , the VALUE of a is [ 47/12 ]

47.

3/4+11/2=7/12+a solve

Answer»

$\frac{3}{4} + \frac{11}{2} = \frac{7}{12} + a$

$\frac{(3 + 22)}{4} = \frac{7}{12} + a$

$\frac{25}{4} = \frac{7}{12} + a$

$a = \frac{25}{4} - \frac{7}{12}$

$a = \frac{75 - 28}{12}$

$a = \frac{47}{12}$

Therefore , the VALUE of a is [ 47/12 ]
