Question

(2/3)^-2
who will give me correct answer i will give him 100 points

Answer 1

To solve:

$\tt \hookrightarrow\bigg(\dfrac{3}{2}\bigg)^{-2}$

Solution:

To make exponent  positive of any rational number, we have to reciprocate it.

So,

$\tt \hookrightarrow\bigg(\dfrac{3}{2}\bigg)^{-2}$

$\tt \hookrightarrow\bigg(\dfrac{3}{2}\bigg)^{2}$

Now squaring of both numerator and denominator.

$\tt \hookrightarrow\dfrac{3^2}{2^2}$

$\tt \hookrightarrow\dfrac{9}{4}$

This is your final answer.

Hope it helps :)
