\[\huge\rm x^m \times x^n = x^{m+n}\] when multiply same bases , add their exponents

imqwerty (imqwerty):

YES

Nnesha (nnesha):

and if there is a negative sign then u should flip it \[x^{-m} = \frac{ 1 }{ x^m }\]

OpenStudy (anonymous):

oh ok

Nnesha (nnesha):

\[\huge\rm \frac{5^{-12}}{1} = ??\] flip the fraction to change the sign of exponent

OpenStudy (anonymous):

ok so d i have to divide or???
