Answer 1

To subtract the two numbers \(4.66 \times 10^{-5}\) and \(7.34 \times 10^{-7}\), we need to express them with the same exponent.

First, let's express \(7.34 \times 10^{-7}\) in terms of \(10^{-5}\):

\[ 7.34 \times 10^{-7} = 0.0734 \times 10^{-5} \]

Now we can rewrite the subtraction:

\[ 4.66 \times 10^{-5} - 0.0734 \times 10^{-5} \]

Next, we perform the subtraction:

\[ = (4.66 - 0.0734) \times 10^{-5} = 4.5866 \times 10^{-5} \]

The result of the subtraction is:

\[ 4.5866 \times 10^{-5} \]

So the correct answer is:

4.5866 x 10^-5

Answer 2

Answer 3

Yes, let's double-check the calculation step-by-step to ensure accuracy.

We have two numbers:

1. \(4.66 \times 10^{-5}\)
2. \(7.34 \times 10^{-7}\)

To perform the subtraction, we need to express both numbers in terms of the same exponent.

Let's convert \(7.34 \times 10^{-7}\) to the same exponent as \(4.66 \times 10^{-5}\):

\[ 7.34 \times 10^{-7} = 0.0734 \times 10^{-5} \]

Now, we rewrite the subtraction:

\[ 4.66 \times 10^{-5} - 0.0734 \times 10^{-5} \]

Now, perform the subtraction:

\[ = (4.66 - 0.0734) \times 10^{-5} \] \[ = 4.5866 \times 10^{-5} \]

Thus, the result is indeed:

\[ 4.5866 \times 10^{-5} \]

Therefore, my previous answer is correct. The answer is:

4.5866 x 10^-5.
