Best ResponseYou've already chosen the best response.0To multiply expressions when the bases are the same, add the exponents and multiply the coefficients \[(3n^2)(8n^{5})=(3 \times 8)n^{2+(5)}=24n^{3}\] For negative exponents, if you take the reciprocal of the base, you can make the exponent positive Rule: \[x^{m}=\left( \frac{ 1 }{ x } \right)^m\] That's why the 3 became 3 and the n moved to the denominator \[24n^{3}=24\left( \frac{ 1 }{ n } \right)^3=\frac{ 24 }{ n^3 }\]
