Question 365019: (6.8 * 10^-6) (9.6 * 10^13) / (2 *10) (3 * 10^9)

ok i already know that -6 and 13= 7 and that when you divide exponents you subtract top and bottom so 7 -9 =-2
the answer is 1.088 * 10 ^-2 i do know how -2 came about but can someone show me how the 1.088 came about because 6.8 * 9.6=65.28 /3=10.88 can anyone show me why the first part of the answer is 1.088? and not 10.88

When the base is 10 or greater, convert it so it's between 1 and 10.

(6.8 * 10^-6) (9.6 * 10^13) / (2 *10) (3 * 10^9)
= 6.8*9.6E7/6E10 (assuming 2 *10 is meant to be 20)
= 6.8*1.6E-3
= 10.88E-3
= 1.088E-2 or 1.088*10^-2
= 0.01088
