Express the number appearing in the following statement in standard form.

Charge of an electron is 0.000,000,000,000,000,000, 16 coulomb.

Solution

∵  0.000,000,000,000,000,000, 16
                               equals 16 over 100000000000000000000
                               
                                equals space fraction numerator 1.6 cross times 10 over denominator 10 to the power of 20 end fraction space equals space fraction numerator 1.6 over denominator 10 to the power of 19 end fraction space equals space 1.6 space cross times space 10 to the power of negative 19 end exponent
