Question

Find the Value of the expression z³-2 (z-10) for z=10​

Answer 1

Evaluating the value of z=10

10*10*10 - 2 (10-10)
1000 - 2(0)
998-0
998

Answer 2

The answer is 100.

The given equation is :  z³-2 (z-10)

We need to find the value of the equation by putting the value of z = 10

Therfore we have

z³-2 (z-10) = $10^{3}$  - 2(10 - 10) =$10^{3}$ - 2x0 = 1000 -0 =1000

In order to find the value of this equation we need to put the value of z in the equation and solve the equation by applying BODMAS rule
