Answer:

I'm assuming you want me to do 18-23? Okay:

Explanation:

18) 8.6(10^−4)+6.7(10^−5)

=0.000927 --> 9.27 × 10^-4

19) 3.5(10^3)−9(10^1)

=3410 --> 3.41 × 10^3

20) 5.6(10^4)(4.5(10^6))

=252000000000 --> 2.52 × 10^11

21) 7.6(10^−7)(8.9(10^−2))

=0 --> 0

22) 3.9(10^−12)/4(10^4)

=0 --> 0

23) 1.75(10^5)/5(10^−3)

=35000000 --> 3.5 × 10^7

Please comment below if you would like me to solve #24 :)

The bolded numbers are the answer, the underlined numbers are to show the question number. Hope this helped !!
