The sqrt() function returns the square root of a number:

> sqrt(25)
[1] 5

The command x^2 raises a number of x to the power 2:

> 4^2
[1] 16

However when those functions are applied to a vector or matrix then, the sqrt() function returns the square root of each element of a vector or matrix. The command x^2 raises each element of x to the power 2; any powers are possible, including fractional or negative powers.

Question

• Take the square root of each element of the matrix x and store it in the variable x.sqrt
• Raise each element to the power 2 of the matrix x and store it in x.squared

Use the code below as a starting point.
