Answer is <span>C) 1/20 of a foot
1/4 -1/5
= 5/20 - 4/20
=1/20</span>
The answer is 7,069.92. You can get this by substituting the known values into the given equation, or I = 22660*13%*2.4. Then, multiply. Make sure to convert 13% to a decimal by moving the decimal point 2 places to the left, which will give you 0.13.
They can be equal if the absolute value of b is 1.
First, we get rid of the negative exponent in the parenthesis. We do this by moving it to the top. Our equation is now:

Next, we can cross out one n from both the top and the bottom.

Finally, we evaluate the -2
Our equation becomes:

This becomes:

This can not be simplified any further, so this is the final answer.
