What does product rule of exponents say
LuckyWell [14K]
The rules of exponents are
( x^{m})( x^{n})=( x^{m+n})
\frac{ x^{m} }{ x^{n} } = x^{m-n}
x^{ \frac{m}{n} } = \sqrt[n]{ x^{m} }
( x^{m} )( y^{m} )=(yx)^{m}
( x^{m})^{n}=x^{mn}
( \frac{x}{y})^{m}= \frac{x^{m}}{y^{m}}
x^{-n}= \frac{1}{x^{n}}
these are just some basic ones
