1. x = 20 , x² = 400 and x³ = 8000
2. x = 7 , x² = 49 and x³ = 343
Step-by-step explanation:
Given values are;
2000, 7, 400, 20, 4000, 200
We have to find x, x² and x³.
Part 1:
We will take cube root to find x.
Now, we will take square;
Therefore;
x = 20 , x² = 400 and x³ = 8000
Part 2:
x² = 49 , x³ = 343
Taking square root on x²
Therefore;
x = 7 , x² = 49 and x³ = 343
