Question

If m= 3 and n=2 Find (i) 9m2 - 10n2 (ii) mpower n - npower m​

Answer 1

Answer:

step:

m=3 n=2 9m2= 9m= 9×3=27×2=54

so 9m2=28 10n2 10×2=20×2=40

1 ans =54

2 ans = 40

Answer 2

Answer:

The answer to the first equation is 41.

The answer to the second equation is 1.

Step-by-step explanation:

Here we have given two equations and the condition is such that m=3 and n=2.

i- 9m²-10n²

ii- $m^{n}$-$n^{m}$

To solve the above equations we need to substitute 3 and 2 at the place of m and n respectively as shown below:

9m²-10n²

=9×3×3-10×2×2

=81-40

=41

The answer to the first equation is 41.

$m^{n}$-$n^{m}$

=$3^{2}$-$2^{3}$

=9-8

=1

The answer to the second equation is 1.
