Answer:
f = 100
Step-by-step explanation:
We need to solve for f.
Since f is raised to the second power, or being squared, we need to do the reciprocal operation. That's just a fancy way of saying the opposite of what is already being done.
What is the opposite of squaring?
Finding the square root!
Find the square root:
f² = 10000
√f² = 10000
Remember, whatever you do on the left side of an equation do to the right.
√f² = √10000
Solve:
√f² = √10000
f = 100
Therefore, f is equal to one hundred.
