Question

(9.50x10^-5)(8.56x10^5)

Answer 1

1.11 x 10⁻¹⁰

Explanation:

Expression of the this form can be solved using one of the rules of solving indices.

 Given expression:

           $\frac{9.50 x 10^{-5} }{8.56 x 10^{5} }$

The most appropriate rule of indices to solve this is;

      $\frac{ a x b^{c} }{d x b^{f} } = \frac{a}{d} x b x ^{c-f}$

   = $\frac{9.5 }{8.56} x 10^{-5-(5)}$

   = 1.11 x 10⁻¹⁰
