I need help on this

I need help on this problem it is
multiply or divide.Express your answer in scientific notation
(5.7x10to the 6 power)(1.2x10 to the -2 power.)

Just multiply the numbers and add the exponents.

BTW You should write it as
(5.7x10^6)(1.2x10^-2) or if you prefer
(5.7x10E6)(1.2x10E-2) is ok too.
