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:

$x^3=8000$

We will take cube root to find x.

$\sqrt[3]{x^3} =\sqrt[3]{8000}$

$x=20$

Now, we will take square;

$(x)^2=(20)^2\\x^2=400$

Therefore;

x = 20 , x² = 400 and x³ = 8000

Part 2:

x² = 49 , x³ = 343

Taking square root on x²

$\sqrt{x^2}=\sqrt{49}\\x=7$

Therefore;

x = 7 , x² = 49 and x³ = 343
