No; 10^7 ÷ 10^(-7) = 10^14.

No, 10^7 and 10^7 cancel when divided. The exponents of 10^7 and 10^-7 add up when divided.

So, ignoring the 3.00 and 4.45, you would have 10^14.

= 3 x 10^7 / 4.45 x 10^-7

= 3 / 4.45 x 10^7 / (1/10^7)

= 3/4.45 x 10^7 x 10^7

= 3/4.45 x 10^14

Nope they don't get cancelled.

See, you can write a^-4 as 1/a^4

Hardly. 10^7/10^(-7) = 10^(14)

x^m/x^n=x^(m-n)

here,

(3/4.45) x 10^14 , because 7-(-7)=14

0.674 x 10^14=6.74 x 10^13

God bless you.
