Question

Evaluate. (a−2b)3 when a=−2 and b=−12

Answer 1

Step-by-step explanation:

(a−2b)

3

\{ - 2 - (2 \times - 12) \}{−2−(2×−12)}

\{ - 2 - ( - 24)\}{−2−(−24)}

\{ - 2 + 24 \}{−2+24}

2222

the required value is 22

Answer 2

let's evaluate :

• $(a - 2b) {}^{3}$

• $\{ - 2 - (2 \times - 12) \}$

• $\{ - 2 - ( - 24)\}$

• $\{ - 2 + 24 \}$

• $22$

the required value is 22
