Question 318859
9m^3=64n^2
since i dont know what your trying to solve as in solve for n or solve for m or just simplify or factor. i will go through some different possibilities

1) {{{(3m)^3=(8n)^2}}}
2) {{{sqrt((3m)^3)=sqrt(8n)^2}}}
___{{{(3m)sqrt(3m)=8n}}}
___{{{((3m)sqrt(3m))/8=n}}}
3) {{{3sqrt((3m)^3)=3sqrt((8n)^2)}}}___{{{3sqrt(8n)}}}means 3rd root of 16n
___{{{(3m)=3sqrt((8n)^2)}}}
___{{{m=(3sqrt((8n)^2))/3}}}
