Answer:
1
Step-by-step explanation:
(2^3 x 2^-1) / 2^2
First, solve what's in the parentheses remembering that when two exponents have the same base and are being multiplied together, their exponents add together:
3 + (-1) = 2
(2^2) / 2^2
And when two exponents with the same base are being divided by each other, the exponents subtract:
2 - 2 = 0
(2^0)
And any number to the power of 0 equals 1:
(2^0) = 1
Hope this helps!
