Answer:

2.2 * 10 ^7

Step-by-step explanation:

3.4 * 10 ^7 - 1.2 * 10 ^7

Since the exponent is the same we subtract the numbers out front

3.4-1.2 = 2.2

Put back the power

2.2 * 10 ^7

This is still in scientific notation

Write 1.2 x 10-4 in decimal form.
katrin [286]

The number (in scientific notation) is:

1.2\times10^{-4}

The power of "-4" tells us to move the decimal point 4 places to the left.

So, moving it, the number becomes:

1.2\times10^{-4}=0.00012
