Need help with a problem

[pooga]

Perform the computations. Write answers in scientific notation.

1x10*10^-8/4x*10^7

So far I have 1/4*10^-8/10^7

1/4*10^-8^-(7)

(0.25)^10^15

Here is where I am having the problem. I am not sure how to write the scientific notation of (0.25) is it 10^-1?

Please try a little harder to write clearly.

This? $\displaystyle \frac{10 \cdot 10^{-8}}{4x \cdot 10^{7}}$
