The square root of a number would be the inverse of an exponent.
so let’s say you have 9 to the 2nd power, or 9^2, it would be 81, because 9 multiplied by itself 2 times (hence the exponent, second power) would be 81.
now, the square root of 9 would be the number that, multiplied by itself 2 times, would be equal to 9.
3 times 3 is equal to 9, and since 3 is being multiplied by itself two times to get 9, the square root of 9 is 3.
does this make sense now?

Answer:
mi = 45(hr)
hr = mi/45
Step-by-step explanation:
Distance = 45 mph times the number of hours (time) D = 45t
time in hours = the number of miles (Distance) divided by 45 mph t = D/45
