An example should help :-
Simplify sqrt 20:-
sqrt 20 = sqrt (4 * 5) = sqrt 4 * sqrt5 = 2 sqrt5
cube root of 54 = cube root 27 * cube root 2 = 3 cube root 2
The rule is to factor the number and look for perfect squares or cubes, etc.

Answer:
x =
Step-by-step explanation:
To solve for x, we need to isolate it [get it alone on one side]
We should start by simplifying (combining the like-terms of our equation):
5 + 5 = 5x + 5 - 2
10 = 5x + 3
- 3 - 3 (subtract 3 from both sides to isolate x)
7 = 5x
÷5 ÷5 (divide both sides by 5 to find "1"x)
So, x =
(x = 7/5)

if u either multiply or divide a number from one side, u must do the same calculation to the other side. hope that helps :)
