Question

Multiply (2.86 × 10−9)(9.2 × 1015). Write the final answer in scientific notation.

Answer 1

2.6312 x 10^7

Explanation:

Answer 2

To multiply these two numbers in scientific notation, you can first multiply their coefficients and then add their exponents:

(2.86 × 10^(-9))(9.2 × 10^15) = (2.86 * 9.2) × (10^(-9) * 10^15)

Now, multiply the coefficients:

2.86 * 9.2 = 26.312

Next, add the exponents:

10^(-9) * 10^15 = 10^(-9 + 15) = 10^6

Now, combine the coefficient and the exponent:

26.312 × 10^6

To express this in scientific notation, you want a coefficient between 1 and 10. In this case, you can write it as:

2.6312 × 10^7

So, the final answer in scientific notation is 2.6312 × 10^7.
