Answer»

Answer:

3+root8

Step-by-step explanation:

1/root9-root8

simplify these with rationalization

multiply num. and den. with terms in den. of ORIGINAL fraction with a sign CHANGE in between

i.e

(1/root9-root8) * (root9+root8/root9+root8)

=root9+root8/(root9^2-root8^2)  (we used FORMULA (a+b)(a-b)=a^2-b^2  )

=root9+root8/(9-8)

=root9+root8

=3+root8

Prove that√2+√3+√5+√7 is irrational number

Answer»

Answer:

  • Let's TAKE that ✓2 is a rational number where √2 = p/q and are in their LOWEST terms.

p^2= 2q^2

p^2 is a multiple of 2

hence, p is a multiple of 2

let P= 2m

(2m)^2 = (√2q)^2

4m^2 = 2q^2

2m^2= q^2

q^2 is a multiple of 2

q is a multiple of 2

it is against our assumptions and hence it is proved that √2 is irrational.

Let's take that ✓3 is a rational number where √3 = p/q and are in their lowest terms.

p^2= 3q^2

p^2 is a multiple of 3

hence, p is a multiple of 3

let P= 2m

(3m)^2 = (√3q)^2

9m^2 = 3q^2

3m^2= q^2

q^2 is a multiple of 3

q is a multiple of 3

it is against our assumptions and hence it is proved that √3 is irrational.

  • Let's take that ✓5 is a rational number where √5 = p/q and are in their lowest terms.

p^2= 5q^2

p^2 is a multiple of 5

hence, p is a multiple of 5

let P= 5m

(5m)^2 = (√5q)^2

25m^2 = 5q^2

5m^2= q^2

q^2 is a multiple of 5

q is a multiple of 5

it is against our assumptions and hence it is proved that √5 is irrational.

  • Let's take that ✓7 is a rational number where √7 = p/q and are in their lowest terms.

p^2= 7q^2

p^2 is a multiple of 7

hence, p is a multiple of 7

let P= 7m

(7m)^2 = (√7q)^2

49m^2 = 7q^2

7m^2= q^2

q^2 is a multiple of 7

q is a multiple of 7

it is against our assumptions and hence it is proved that √7 is irrational.

Above it is clearly proved that 2 , 3 , 5 and 7 are irrational.

"The SUM of irrational numbers will always be irrational. "

hence it is proved that the sum of 2 , 3 , 5 and 7 will be an irrational number.

hope it helps!

By selling 5 bananas a rupees a man lost 20%.if he had 12 dozen bananas with him what was the c.p.and s.p. of the bananas

Answer»

Given:

By selling 5 bananas a rupees a man lost 20%.

If he had 12 dozen bananas with him

To find:

What was the c.p.and s.p. of the bananas?

Solution:

S.P. of 5 bananas = Re. 1

So, S.P. of 1 banana = Rs. \frac{1}{5}

∴ C.P. of 1 banana is,

=  \frac{100}{100 - Loss\%} \times S.P.

= \frac{100}{100 - 20} \times \frac{1}{5}

= \frac{100}{80} \times \frac{1}{5}

= \frac{1}{<klux>4</klux>}

We know,

\boxed{\bold{1 \:dozen = 12\: bananas}}

∴ 12 dozen bananas = 12 × 12 = 144 bananas

Now,

C.P. of 144 bananas = C.P. of 1 banana × 144 = \frac{1}{4} \times 144 = Rs. \: 36

and

S.P. of 144 bananas = S.P. of 1 banana × 144 = \frac{1}{5} \times 144 = Rs. \: 28.8

Thus, the C.P. of the bananas is Rs. 36 and the S.P. of the bananas is Rs. 28.8.
