#3.5 xx 10^-15#

Use the exponent Rule # x^m/x^n = x^(m-n)#

#8.4/2.4 * 10^(-6 -9) = 3.5 xx 10^-15#

Answer 2 · 2017-03-30T18:36:33

#color(red)(3.5 xx 10^-15#

#(cancel8.4^color(red)3.5 xx 10^-6 )/(cancel2.4^color(red)1 xx 10^9)#

#:.=(3.5 xx 10^-6)/10^9#

exponentiol rule:

#:.(a^m)/(a^n)=a^(m-n)#

#:.=3.5 xx 10^(-6-9)#

#:.=color(red)(3.5 xx 10^-15#
