Given:
The equation is

To find:
The value of x.
Solution:
We have,

![[\because \left(\dfrac{a}{b}\right)^{-m}=\left(\dfrac{b}{a}\right)^{m}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5E%7B-m%7D%3D%5Cleft%28%5Cdfrac%7Bb%7D%7Ba%7D%5Cright%29%5E%7Bm%7D%5D)
![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)

On comparing the exponents, we get

Therefore, the value of x is 3.

Answer:
<h3>96 is the answer. </h3>
Step-by-step explanation:
<h3>The L.C.M of 8 and 12 is 24</h3><h3>The H.C.F of 8 and 12 is 4</h3>
<h3>We multiply </h3><h3>24 *4 we shall get 96 as the answer. </h3><h3 />

I always start by moving the last term to the other side

To complete the square you take term 'b' , divide it by 2 then square it

= 25
We have to add 25 to what we have and what you do to one side you have to do to the other


Now we factor what is on the left side of the equation

The last step is to move our right side of the equation back over

- which is your answer :)))
