Question

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

Answer 1

Answer:

C.)   8.68686 × $10^{7}$

D.)   4.1688 × $10^{2}$

Step-by-step 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 × $10^{2}$ ****
