7.00 x 10 to the eight power divided by 7.00 x 10 to the ninth power?

(7 x 10^8)/(7 x 10^9)
= (7/7)(10^8/10^9)
= 1(1/10)
= 1/10 (0.1)

it may be to the eighth potential! you may count type the zeros plus the three digits interior the decimal. that's 3 + 5 = 8. or in simple terms carry the decimal back 'til you have 5 zeros and count type what share situations you push it back.

7 x 10^8
----------
7 x 10^9

1/10

= 7∙00*10^8 / 7∙00*10^9
= 1*10^8 / 1*10^9
= 1 / 1*10¹
= 1 /10
= 0∙1

That is simple subtraction. It is -1 (7.00x10 (8))/(7.00x10 (9))=(7.00x10 (-1))

(7.00 * 10^8) / (7.00 * 10^9)

The 7s cancel.
10^8/10^9 =

Remember: x^a/x^b = x^(a-b)
10^8/10^9 =
10^(8-9) =
10^(-1) =

Remember: x^(-a) = 1/x^a
10^(-1) =
1/10

Also can be written as 0.1

7/7 = 1 10^8/10^9 = either 1/10 or 10^-1
Combine and you have 0.1

Divide the numbers = 7/7 = 1
subtract the exponent of the den. = 8-9 = -1
1x10^(-1) = 0.1

(7.00×10⁸)/(7.00×10⁹) = 1/(10⁹⁻⁸)
= 1/10¹
= 0.10
