Question

if 3m-2n=5 mn=6then find the values of 27m cube - ncube

Answer 1

HEY FRND HERE IS UR ANSWER.

3m-2n=5 mn=6

n=6/m

3m-2(6/m)=5

3m-12/m=5

3m²-12=5m

3m²-5m-12=0

3m²-9m+4m-12=0

3m(m-3)+4(m-3)=0

m=3

FROM THIS, n=2

GIVEN

27m³-n³=(3m)³-n³

NOW SUBSTITUTE THE VALUES OF m AND n.

HOPE MY ANSWER WILL BE HELPFUL 2 U.
