216

Explanation:

$2 b$ $2b$ means $2 \times b$ $2xxb$ .

Note that ${(2 b)}^{3}$ $(2b)^3$ and $2 b^{3}$ $2b^3$ are different. In the first case, the power, 3 is applied to the multiple of $2$ $2$ and $b$ $b$ , whereas in the second case, the power is applied to $b$ $b$ only.

Coming back to the question,

${(2 b)}^{3} = {(2 \times 3)}^{3} = 6^{3} = 6 \times 6 \times 6 = 216$ $(2b)^3 = (2xx3)^3 = 6^3 = 6xx6xx6 = 216$
