-----------------------------
7.3 x 10^-16

1 answer

Let's compute the given expression step-by-step.

The expression is:

\[ \frac{(8.2 \times 10^{-3}) \times (-7.9 \times 10^{7})}{7.3 \times 10^{-16}} \]

First, we'll calculate the numerator:

\[ (8.2 \times 10^{-3}) \times (-7.9 \times 10^{7}) = (8.2 \times -7.9) \times (10^{-3} \times 10^{7}) \]

Calculating \(8.2 \times -7.9\):

\[ 8.2 \times -7.9 = -64.78 \]

Now, multiplying the powers of ten:

\[ 10^{-3} \times 10^{7} = 10^{-3 + 7} = 10^{4} \]

So, the numerator is:

\[ -64.78 \times 10^{4} \]

Now, let's divide this result by the denominator \(7.3 \times 10^{-16}\):

\[ \frac{-64.78 \times 10^{4}}{7.3 \times 10^{-16}} = \frac{-64.78}{7.3} \times \frac{10^{4}}{10^{-16}} \]

Calculating \(\frac{-64.78}{7.3}\):

\[ \frac{-64.78}{7.3} \approx -8.86 \quad (\text{rounded to two decimal places}) \]

Now, calculating \(\frac{10^{4}}{10^{-16}}\):

\[ 10^{4} \times 10^{16} = 10^{4 + 16} = 10^{20} \]

Putting it all together:

\[ -8.86 \times 10^{20} \]

Therefore, the final result of the expression is approximately:

\[ -8.86 \times 10^{20} \]
