Question

PLEASE HELP WITH STEPS!!!!!!! ANSWER IN SCIENTIFIC NOTATION I WILL GIVE BRIANLIEST

Answer 1

C.) 8.68686 ×
`10^(7)`

D.) 4.1688 ×
`10^(2)`

Explanation:

For C.) you take 8.69 and multiply that by
`10^(7)` and you'll get 86900000

Then you take 3.14 and multiply that by
`10^(4)` and you'll get 31400

So then you take 86900000 and 31400 and subtract it...

86900000 - 31400 = 86868600 and you convert 86868600 to scientific Notation.

Which would equal **** 8.68686 ×
`10^(7)` *****

For D.) you take 4.32 and multiply that by
`10^(3)` and You'll get 4320

then you take 9.65 and multiply that by
`10^(-2)` and you'll get 0.0965

So then you take 4320 and 0.0965 and subtract it...

4320 - 0.0965 = 4319.9035 and you convert 4319.9035 to Scientific Notation.

Which would equal **** 4.1688 ×
`10^(2)` ****
