Subtract 4.66 × 10^−5 −7.34 × 10^−7

To subtract these numbers in scientific notation, we need to have the same exponent for both numbers.

First, let's rewrite both numbers with the same exponent:

4.66 × 10^(-5) = 0.0000466
7.34 × 10^(-7) = 0.000000734

Now, we can subtract these two numbers:

0.0000466 - 0.000000734 = 0.000045866
