Answer:
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.
