Question 773547: if P=18, Q=21, R=-6,and S=-4, calculate(P-Q)power3/R power3+Spower2

You can put this solution on YOUR website!
(P - Q)^3
(18 - 21)^3
(-3)^3
= -27
R^3
= -6^3
= -216
S^2
-4^2
= 16
(P-Q)power3/R power3+Spower2
-27/-216 + 16
Common Denominator -216
(-27 + -3456)/-216
= 16.125
Hope this helps.
