In step 1 the difference of 1.5x(-3.2) & 1.5x(2.5) should be written as a sum. Hope that’s right :).
A triangle can't have two right angles because there is 180° in a triangle. Each right angle is 90° so it would be impossible
Given:
Consider the given equation is:

To find:
The missing exponent.
Solution:
Let x be the missing exponent. Then the given equation can be written as

It can be rewritten as:

![[\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 coefficient of m, we get



Therefore, the value of the missing exponent is 8. So, the complete equation is
