I need help 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. Please see the attached file.

Only number 14, PLEASE Briefly explain step by step to me for everything you do. Thanks.

Answer: x = 3

Step-by-step explanation:

[tex](8)\bigg(\dfrac{2}{3}\bigg)^x=(4)\bigg(\dfrac{16}{27}\bigg)\\\\\\\bigg(\dfrac{2}{3}\bigg)^x=\bigg(\dfrac{4}{8}\bigg)\bigg(\dfrac{16}{27}\bigg)\\\\\\\bigg(\dfrac{2}{3}\bigg)^x=\bigg(\dfrac{1}{2}\bigg)\bigg(\dfrac{16}{27}\bigg)\\\\\\\bigg(\dfrac{2}{3}\bigg)^x=\bigg(\dfrac{8}{27}\bigg)\\\\\\\bigg(\dfrac{2}{3}\bigg)^x=\bigg(\dfrac{2^3}{3^3}\bigg)\\\\\\\bigg(\dfrac{2}{3}\bigg)^x=\bigg(\dfrac{2}{3}\bigg)^3\\\\\\x=3[/tex]
