Question 75660
By "solve" I expect you "simplify"
Simplify:
{{{((2m^3x^2)^(-1)(3m^4x)^(-3))/(m^2x^3)^3(m^2x)^(-5)}}}

Now multiply the exponents inside the parenthese by the ones outside the parentheses.
{{{((2^(-1)m^(-3)x^(-2))(3^(-3)m^(-12)x^(-3)))/(m^6x^9)(m^(-10)x^(-5))}}}

Combine like-factors:
{{{(2^(-1)(3^-3)m^(-15)x^(-5))/(m^-4)x^(4)}}}
Remember that you can change the sign of the exponents by moving the factor down or up as the case maybe.
To simplify this expression, you want all the exponents to be positive.
{{{(m^4)/((2^1)(3^3)m^15x^9)}}} 
{{{m^4/(2*27*m^15(x^9)) = 1/54m^11(x^9)}}}
