Question

1.4 x 10^-5 / 5x10^2
please make it simple so I aan write it down

Answer 1

To simplify the expression \( \frac{1.4 \times 10^{-5}}{5 \times 10^2} \), you can follow these steps:

1. Divide the numerical coefficients:
\( \frac{1.4}{5} = 0.28 \)

2. Subtract the exponents of 10:
\( 10^{-5} / 10^{2} = 10^{-5 - 2} = 10^{-7} \)

Now, combine the results:
\( 0.28 \times 10^{-7} \)

Finally, you can rewrite it in proper scientific notation:
\( 2.8 \times 10^{-8} \)

So, the simplified expression is:

\[
2.8 \times 10^{-8}
\]
