Question 757358
what is x to the seventh power divided by x to the negative second power? The book says the answer is x to the ninth power but how?
:
{{{x^7/x^-2}}}
remember you can get rid of the negative exponent by writing the 
reciprocal, therefore
{{{x^7}}}*{{{x^2/1}}} or just {{{x^7*x^2}}}
add exponents when you multiply
{{{x^9}}}
