x = ±4
x = 4
Step-by-step explanation:
x² = 64.
Square root both sides
√x² =√64
x= ±8
When squaring both sides, the required solution is both positive and negative since the product of two negative number is positive.
x³ = 63.
Cube root both sides
3√x³ = 3√65
x =4
This only gives a positive number not negative since the product of three negative number gives a negative number
