Question

If z=5, find the value of z^3 -3 (z-10)​

Answer 1

Answer:

${z}^{3} - 3(z - 10) \\ z = 5 \\ = {(5)}^{3} - 3(5 - 10) \\ = 125 - 3 \times - 5 \\ = 125 + 15 \\ = 140$

Answer 2

Answer:

-610

Step-by-step explanation:

when z=5,

put z=5 in equation z^3-3(z-10)

= 5^3-3(5-10)

= 125-3(-5)

= 122(-5)

= -610
