To subtract these numbers, we need to have the same exponent for the 10.
Let's write both numbers with the same exponent (we'll use -5):
4.66 x 10^-5 - 7.34 x 10^-7
= 4.66 x 10^-5 - 0.0734 x 10^-5 (we move the decimal point two places to the left in 7.34)
Now that the exponents are the same, we can subtract the numbers in front:
= (4.66 - 0.0734) x 10^-5
= 4.5866 x 10^-5
Therefore, 4.66 x 10^-5 - 7.34 x 10^-7 = 4.5866 x 10^-5
Subtract 4.66 x 10^-5 - 7.34 x 10^-7 (1 point)
