Answer: [tex]\frac{1}{25}k^2[/tex]
This is equivalent to [tex]\frac{k^2}{25}[/tex]
In decimal form, this is equivalent to 0.04k^2
==================================
Work Shown:
We have the two pieces 1/5 and k, all in the parenthesis being squared.
Square each piece
- Squaring the piece 1/5 leads to (1/5)^2 = 1/25, since 5^2 = 25
- squaring the k value leads to k^2
So overall, we end up with the answer [tex]\frac{1}{25}k^2[/tex] which is equivalent to saying [tex]\frac{k^2}{25}[/tex]
In decimal form, this is 0.04k^2 because 1/25 = 0.04
