subtract 4.66 x 10^-5 -7.34 x 10^-7

Answer 1

To subtract these two numbers, we need to have them both written in the same scientific notation form.

4.66 x 10^-5 can be written as 0.0000466 in decimal form.

-7.34 x 10^-7 can be written as -0.000000734 in decimal form.

Now we can subtract them:

0.0000466 - 0.000000734 = 0.000045866

Converting this back to scientific notation, we have:

4.5866 x 10^-5
