Ineed on how to solve these types of questions. not the answer. the section is on exponential equations. it has to do something with a(b)^x

this is confusing because on number 12 it is not same format for number 14. idk it looks weird because there is parentheses around a lot of numbers. see the attached file.

11. Divide both sides by 2:

The solution has to be because

12. Divide both sides by 2:

On the right side we have two perfect squares:

so again the answer is .

14. Divide both sides by 8:

On the right we have perfect cubes:

so .

15.

We could divide both sides by 2/5 (or multiply both sides by 5/2, as the writing on your paper suggests). Then

The right side has two perfect squares:

so that .

Another way to do this is to rewrite the left side as

Meanwhile, on the right we have two perfect cubes:

so that , or , as before.
