Question

9m² – 10n³, Find the value of If m = 3 and n = 2.

Answer 1

Solution :

If m = 3 and n = 2 ,

Value of 9m² - 10n³

= 9 × 3² - 10 × 2³

= 9 × 9 - 10 × 8

= 81 - 80

= 1

Answer 2

$\bold{\huge{\underline{\underline{Answer}}}}$

$\bold{\large{\underline{Given\: \colon}}}$

m = 3 and n = 2

$\bold{\large{\underline{To\: find\: \colon}}}$

9m² - 10n³

$\bold{\large{\underline{Solution\: \colon}}}$

m = 3 and n = 2

Put the value of m and n in equation :

$\implies \bold{\large{ 9m^{2} \: - \: 10 n ^{3} }}$

$\implies \bold{\large{ 9(3)^{2} \: - \: 10 (2)^{3}}}$

$\implies \bold{\large{ 9(9) \: - 10(8)}}$

$\implies \bold{\large{ 81 \: - \: 80}}$

$\implies \bold{\large{ 1 }}$

$\bold{\large{\underline{Answer\: \colon}}}$

$\bold{\large{\boxed{ 9m^{2} \: - \:10n^{3} \: = \: 1}}}$
