What is the value of x in x2 1024 What is the value of x in

What is the value of x in x^2 = 10.24? What is the value of x in x^3 = 512? Carl is enclosing a square garden with a fence. The area of the garden is 237.16 square feet. How long, in feet, is each side of the garden?

Solution

Here are the solution to the problems:

1)

x^2 = 10.24
x^2 = 4*256 / 100
x=2*16/10 = 3.2

2)

x^3 = 521
x^3 = 8*8*8
x=8

3)

Area of garden = a*a = 237.16
The side of sqaure is a.
Therefore, a = sqrt(237.16)=15.4
Side of sqaure fence is therefore, 15.4
