Question 210846
{{{2.22*10^(-12) / 4.1*10^(-33)}}}
Multiply top and bottom by {{{10^33}}}
{{{(2.22*10^(-12) / 4.1*10^(-33)) * (10^33/10^33)}}}
{{{2.22*10^(-12)*10^33 / (4.1*10^-33*10^33)}}}
because the general rule is {{{10^(-a)*10^a = 10^0}}}
and {{{10^0 = 1}}}
{{{2.22*10^(-12)*10^33 / 4.1*1}}}
Another rule is {{{10^(-a)*10^b = 10^(b-a)}}}, so
{{{2.22*10^21/4.1}}}
Change the numerator to an equivilant number
{{{22.2*10^20}}}
{{{22.2*10^20 / 4.1 = 5.41*10^20}}} answer
