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:
[tex]x^3=8000[/tex]
We will take cube root to find x.
[tex]\sqrt[3]{x^3} =\sqrt[3]{8000}[/tex]
[tex]x=20[/tex]
Now, we will take square;
[tex](x)^2=(20)^2\\x^2=400[/tex]
Therefore;
x = 20 , x² = 400 and x³ = 8000
Part 2:
x² = 49 , x³ = 343
Taking square root on x²
[tex]\sqrt{x^2}=\sqrt{49}\\x=7[/tex]
Therefore;
x = 7 , x² = 49 and x³ = 343
