Question 276148
{{{((12x^4)/(18x^3))*(((-8)x^5)/(4x^2))}}}
As you probably know, there are often more than one way to solve a Math problem. So what follows is not the only way to simplify this expression.<br>
I'm going to start by simplifying the fractions before I multiply them. This will reduce the coefficients and exponents, making them easier to work with. 
{{{((12/18)(x^4/x^3))*(((-8)/4)((x^5)/x^2)))}}}
{{{((2/3)x)*((-2)(x^3))}}}
and the fractions are gone!
Now we can multiply:
{{{-(4/3)x^4}}}
