Answer 1

$\huge \fbox \red{❥Answer}$

Given:

z = 10

To find:

z³ - 3(z - 10)

Solution:

z³ - 3(z - 10)

(10)³ - 3(10 - 10)

1000 - 3(0)

1000

Hence the value of z³ - 3(z - 10) is 1000.

Answer 2

Solution⤵

z³ - 3(z - 10)

➥ (10)³ - 3(10 - 10)

➥ 1000 - 3(0)

➥ 1000

Hence the value of z³ - 3(z - 10) is 1000
