Simplify :  space space fraction numerator 2 to the power of negative 5 end exponent cross times 10 to the power of negative 5 end exponent cross times 125 over denominator 5 to the power of negative 9 end exponent cross times 6 to the power of negative 5 end exponent end fraction


Since   125 space equals space 5 space cross times space 5 space cross times space 5 space equals space 5 cubed

           10 to the power of negative 5 end exponent space equals space left parenthesis 2 cross times 5 right parenthesis to the power of negative 5 end exponent space equals space 2 to the power of negative 5 end exponent space cross times space 5 to the power of negative 5 end exponent
6 to the power of negative 5 end exponent space equals space left parenthesis 2 cross times 3 right parenthesis to the power of negative 5 end exponent space equals space 2 to the power of negative 5 end exponent space cross times space 3 to the power of negative 5 end exponent

∴   fraction numerator 2 to the power of negative 5 end exponent cross times 10 to the power of negative 5 end exponent cross times 125 over denominator 5 to the power of negative 9 end exponent space cross times space 6 to the power of negative 5 end exponent end fraction space equals space fraction numerator 2 to the power of negative 5 end exponent cross times 2 to the power of negative 5 end exponent cross times 5 to the power of negative 5 end exponent cross times 5 cubed over denominator 5 to the power of negative 9 end exponent cross times 2 to the power of negative 5 end exponent cross times 3 to the power of negative 5 end exponent end fraction

                     equals open parentheses 2 to the power of negative 5 end exponent over 2 to the power of negative 5 end exponent close parentheses space cross times space fraction numerator 5 to the power of negative 5 plus left parenthesis negative 5 right parenthesis plus 3 end exponent over denominator 5 to the power of negative 9 end exponent cross times 2 to the power of negative 5 end exponent cross times 3 to the power of negative 5 end exponent end fraction

                     equals 1 space cross times space fraction numerator 5 to the power of negative 7 end exponent over denominator 5 to the power of negative 9 space end exponent cross times space 3 to the power of negative 5 end exponent end fraction

                      equals fraction numerator 1 cross times 5 to the power of 9 cross times 3 to the power of 5 over denominator 5 to the power of 7 end fraction

                      equals 1 cross times 5 to the power of 9 minus 7 end exponent cross times 3 to the power of 5

                       = 1 space cross times space 5 squared space cross times space 3 to the power of 5
