Question

Which expression is equivalent to b^m•b^n A. b^m-n B. b^m•n C. b^m÷n D. b^m+n

Answer 1

   
$\displaystyle\\ \bold{b^m \times b^n = b^{m + n}~~~(D)}\\\\ \bold{\frac{b^m}{b^n}= b^{m - n}~~~~~~~~~(A)}\\\\ \bold{\Big(b^m \Big)^n = b^{m\times n}~~~~(B)}\\\\ \bold{\sqrt[\bold{n}]{\bold{b^m}} = b^{m\div n } ~~~~~~(C)}$
