What is the standard form for 56.34 million?

Answer 1

First, let's just get it into the form of (a number)*10(a power), not necessarily correct standard form.

If we write out 1 million, it's 1,000,000. When we count up the zeros, we see this is 106

Thus we can write 56.34 * 106. But in standard form, the decimal one place from the left. For every place we move the decimal to the left, we must add a 1 from the exponent, and for every place we move it to the right, we subtract a 1. If we move the decimal one to the left, it will be in the correct place, thus we must add 1 from the exponent. When we do this we get

5.634 * 107

Which is 56.34 million in standard form.
