Answers
D. 1.26x10^6
To multiply numbers in scientific notation, you first multiply the coefficients (1.8 x 7) and then add the exponents (1 + 5). This gives you 12.6x10^6. However, this number is not written in proper scientific notation because the coefficient should be between 1 and 10. Therefore, you move the decimal point one place to the left, resulting in 1.26x10^7. This matches option A.
