Question 70427
How do you simplify a^6b^-5/a^-2b^7? 
One way to do it is:
{{{a^6b^(-5)/(a^(-2)b^7)}}}
{{{a^(6-(-2))/b^(7-(-5))}}}
{{{a^(6+2)/b^(7+5)}}}
{{{highlight(a^8/b^12)}}}
Another way would be to put the variables with negative exponents up or down, then simplify:
{{{a^6b^(-5)/(a^(-2)b^7)}}}
{{{a^6*a^2/(b^7*b^5)}}}
{{{a^(6+2)/b^(7+5)}}}
{{{highlight(a^8/b^12)}}}
Pick whatever method you like.
Happy Calculating!!!!
