Divide like items, them simplify.
(5.4/6) = 0.9
(10^18 / 10^6) = 10 ^12
*when you divide terms with the same base when solving exponent questions, the shortcut is to subtract the powers.
Write out two solutions as one:
0.9 x 10^12
* scientific notation always needs ONE number between 1-9 in front of the decimal, so you have to move the decimal over to make 9 a whole number and change your power.
Solution:
9 x 10^11
