Question 1030428
Okay, from
{{{(a^3c/ac^4)*(a^3/ac^4)}}}
we can multiply first and then cancel, or cancel first, then multiply...I will show you the first method...
Remember when we multiply fractions, we multiply numerators and denominators across...also multiplying lies bases mean adding exponents...so we get
{{{(a^3c/ac^4)*(a^3/ac^4) = (a^6c)/(a^2c^8)}}}
Now cancel a^2 top and bottom and then cancel c top and bottom giving us
{{{a^4/c^7}}}
