Answer 2

To subtract these two numbers, we need to first convert them to the same powers of 10.

4.66 × 10^(-5) - 7.34 × 10^(-7)

The second number, 7.34 × 10^(-7), is already in the same form. To convert the first number, we can multiply it by 10 to make the exponent -4 (-5 + 1):

4.66 × 10^(-5) = 4.66 × 10^(-4) × 10 = 0.466 × 10^(-4)

Now, we can subtract the two numbers:

0.466 × 10^(-4) - 7.34 × 10^(-7)

To subtract these numbers, the powers of 10 must be the same. We need to convert 0.466 × 10^(-4) to the same power of 10 as 7.34 × 10^(-7), which is -7 (-4 - 3):

0.466 × 10^(-4) = 0.466 × 10^(-4) × 10^3 × 10^(-3) = 0.466 × 10^(-4+3-3) = 0.466 × 10^(-4)

Now that both numbers are in the same form, we can subtract:

0.466 × 10^(-4) - 7.34 × 10^(-7) = (0.466 - 7.34) × 10^(-4) = -6.874 × 10^(-4)

Therefore, the result of subtracting 4.66 × 10^(-5) - 7.34 × 10^(-7) is -6.874 × 10^(-4).

Answer 3

The correct answer is 4.5866×10^(-5).
