On line, exponents are preceded by ^.

2s^3 − 4r^2

Answered by MathPerformer
ok

Solve 2s^3 − 4r^2 if r = 1 and s = 5.

Answered by Ms. Sue
Ahh -- thanks for the correction.

2s^3 − 4r^2
10^3 - 4^2
1,000 - 16 = 984

You are very welcome.
Answered by Reiny
order of operation dictate that you do the exponents first:

2s^3 − 4r^2
= 2(5^3) - 4(1^2)
= 2(125) - 4(1)
= 246
