Google has a calculator that can handle this. https://www.google.com/search?q=3.45+*+10%5E-3

anonymous · Answer

10^-3 is just divide the number by 10 three times or divide by 1000. so 3.45/10 = 0.345, and you have to divide it  by 10 two  more times

I'd suggest you define for  yourself and the rest of us what a number "in standard form" looks like.   Do you mean Engineering notation?  If not, what?

Once you've defined the standard you're going to use, re-writing the given number should be straightforward.

Just write 3.45 x 10^-3 as
0003.45 x 10^-3

You see the exponent is -3 so you have to shift the decimal 3 positions to the left.

By the way, if you want to express "exponentiation" properly, learn how to present negative exponents:
$$3.45 x 10^{^{-3}}$$

Gee I suppose that I now have a smart score of 99, I should learn more about typing things in that "fancy" way.
