evaluate 4 + (m - n)^4 when m = 7 and n = 5. the value of the expression is
Answer
Explanation:
Step1: Substitute values
Substitute $m = 7$ and $n = 5$ into $(m - n)$: $m - n=7 - 5=2$.
Step2: Calculate the power
Calculate $(m - n)^4$, since $m - n = 2$, then $(m - n)^4=2^4 = 16$.
Step3: Add 4
Add 4 to $(m - n)^4$: $4+(m - n)^4=4 + 16=20$.
