Question

Find the value of the expression z3- 2(z- 10) for
z = 10.

Answer 1

Answer:

30

Step-by-step explanation:

z =10

z3- 2(z - 10)

put the value of z in the given eq.

10 × 3 - 2(10 - 10)

30 - 2×0

30

Answer 2

Value of the expression z³ - 2(z - 10) for z = 10 is 1000

Value of the expression z3 - 2(z - 10) for z = 10 is  30

Given:

• Expression
• z³ - 2(z - 10)
• or z3 - 2(z - 10)

To Find:

• Value of the expression for z = 10

Solution:

Step 1:

Substitute z = 10  in z³ - 2(z - 10)

10³ - 2(10 - 10)

Step 2:

Solve the parenthesis

10³ - 2(0)

= 10³ - 0

= 10³

Step 3:

Find value of 10³

10³

= 10 x 10 x 10

= 1000

Hence Value of the expression z³ - 2(z - 10) for z = 10 is 1000

if Expression is z3 - 2(z - 10)

Then 10 (3) - 2(10 - 10)  =  30  

Value of the expression z3 - 2(z - 10) for z = 10 is 30
