Question

Evaluate each expression if r= −3, s=4, and t= −7.

Answer 1

a.
`5`

b.
`-1`

c.
`132`

Explanation:

Given:

`r =-3`,
`s = 4` and
`r = -7`

`√(s) +|r| \\ √(4) +|-3| \\ 2 +3 \\ 5`

`(s -r)/(t) \\ (4 -(-3))/(-7) \\ (4 +3)/(-7) \\ (7)/(-7) \\ -1`

`2s^3 +r -t \\ 2(4)^3 +(-3) -(-7) \\ 2(64) -3 +7 \\ 128 -3 +7 \\ 132`
