Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
To find this, simply subtract 57 from 90. 90 is the measurement for a completed compliment equation, and 57 is the part of the compliment we know.
33 is the answer
The numbers are irrational, so I can't write them exactly with digits.
When rounded to the nearest ten-thousandth, they are
31.3746
and
-6.3746 .
The answer you put is correct
