Question

if m = 3 and n = 3 find 9m²-10n³​

Answer 1

Answer:

9(3)^2-10(3)^3=9(9)-10(27)

=81-270

=. -189

Answer 2

Step-by-step explanation:

Given, n=3, m =3

Now

$= 9 \times {3}^{2} - 10 \times {3}^{3 } \\ = 9 \times (3 \times 3) - 10 \times (3 \times 3 \times 3) \\ = 9 \times 9 - 10 \times 27 \\ = 81 - 270 \\ = - 189$
