-a^2+7b^4-2c^3
-(-4)^2+7(-2)^4-2(-3)^3
= -(16)+7(16)-2(27)
= -16+112-54
=-70+112
=42
Answer:
a=2^2
b=3^5
c=4^3x5^2
d=7^2x9^4
Step-by-step explanation:
All you have to do is write the number that is already there and power it by number of times it is repeated.
If there are two different numbers in a question (like c and d) you should start with the smaller number and then follow with the larger on with a x/times symbol between them.
