If r = 55, then the value of $r(r^2 + 3r + 3)$ is:

Options:

105000

176615

175616

175615

Correct Answer:

175615

Explanation:

If r = 55,

then the value of $r(r^2 + 3r + 3)$

$r(r^2 + 3r + 3)$ = 55(55^2 + 3(55) + 3)

$r(r^2 + 3r + 3)$ = 55(3025 + 165 + 3)

$r(r^2 + 3r + 3)$ = 55(3193)

$r(r^2 + 3r + 3)$ = 175615
