A deposit that is the answer
I believe the answer is 4 from what it looks like it should be because of three lengths on the sides
Answer:
n = 30
Step-by-step explanation:
you want to isolate the n and get it by itself. So you would do the inverse operation. On the other side, you do the same thing.
2^2 , or 4
since the exponents have the same base, we can subtract the exponent of the numerator by the exponent in the denominator.
So 2^-3 - 2^-5 = 2^(-3-(-5)) = 2^2
The new exponent is 2 because -3-(-5) is equal to 2.
