Question

Given m=-2 and n = 6 evaluate​

Answer 1

According to Question

m = -2 and n = 6

Answer:

3×-2³ + 2×-2²×6 + 6³....

= 3×-8 + 12×-2² + 216

= -24 + 48 + 216

=> 24+ 216 = 240

Answer 2

$\mathfrak{\huge{\underline{Answer:}}}$

$\textbf{\underline{\underline{Given\:Equation\:Is :}}}$

$\sf \: 3 {m}^{3} + 2 {m}^{2} n + {n}^{3}$

To Evaluate As. m = -2 and n = 6

$\textbf{\underline{\underline{Putting\:Values :}}}$

$\sf \: 3 {m}^{3} + 2 {m}^{2}n + {n}^{3}$

$\sf \: 3 \times ( { - 2})^{3} +( 2 { \times - 2}^{2} \times 6) + ( { 6})^{3}$

$( \sf \: 3 \times - 8) + (2 \times 4 \times 6) + ( 216)$

$\sf \: - 24 + 48 +216$

$\sf \: -24+264$

$\boxed{\boxed{240}}$
