Move the decimal to the right five places.


Scientific notation just abbreviates long numbers with a ton of zeros (or numbers that might as well be zeros for all the good they're doing you). Because the exponent (5) is positive, you know the number is getting bigger. Therefore, you make the number larger by moving the decimal (after the 23) to the right. If you want to, you can type into a calculator and check.

If the exponent had been negative, you would have moved the decimal to the left, making the number smaller.
