Re: Simplify the expression, All exponents should be positive
I hope I interpret this right.
\(\displaystyle \frac{5^{-6}\cdot x^{-1}\cdot y^{4}}{5^{-3}\cdot x^{-4}\cdot y^{8}}\)
If so, use the laws of exponents. When you divide exponents, subtract them. When you multiply, add them.
So, for a shove in the right direction, \(\displaystyle \frac{5^{-6}}{5^{-3}}=5^{-6-(-3)}=5^{-3}\)
Make sure the bases are the same when you do this.
Do the same with the x's and the y's.
