Question

If m =3 and n=2 find the value of 9m2-8n3

Answer 1

Step-by-step explanation:

IF m= 3 , n =2

9*(3) square - 8* (2) square

(9*9) - (8*4)

81-32

= 49

Answer 2

Answer:

$m = 3 \: \: \: \: \: n = 2$

So,

$(9 {m}^{2} ) - (8 {n}^{3} ) \\ = (9 \times {3}^{2}) - (8 \times {2}^{3} ) \\ = (9 \times 27) - (8 \times 8) \\ = 243 - 64 \\ = 179$
