When multiplying numbers written in scientific notation, multiply the whole numbers first:
3.35 * 2.3 = 7.705
The just add the exponents on the 10's, 25 + 7 = 32
Because when you multiplied the whole numbers there is only one digit to the left of the decimal point, you don't need to add or subtract any exponent, so that will remain as 32
the answer will be 7.705 x 10^32
