Question

What is the value of the expression 3.6 x 10^8 /1.2 x 10^3?
2.4 ⋅ 10^5
3.0 ⋅ 10^11
3.0 ⋅ 10^5
2.4 ⋅ 10^11

Answer 1

\[\frac{ 3.6 \times 10^8 }{ 1.2 \times 10^3 } \implies \frac{ 3.6 }{ 1.2 } \times \frac{ 10^8 }{ 10^3 }\] do them separately, apply exponent rules for the \[\frac{ 10^8 }{ 10^3 }\]

Answer 2

\[\huge \frac{ x^m }{ x^n } = x^{m-n}\]

Answer 3

oh ok so its 10^8/10^3 = 10^8-3

Answer 4

Yes!

Answer 5

which is 10^5

Answer 6

yup

Answer 7

then after that its 3.6/1.2 = 3

Answer 8

Yup :)

Answer 9

so its 10^5 x 3

Answer 10

3 x 10^5, but yes you got the idea!

Answer 11

ya thanks
