Divide 6.41 x 10-3 by 8.04 x 107 and express the answer in scientific notation.

Question

Quizplus · Accepted Answer

To divide two numbers in scientific notation, we need to divide the coefficients and subtract the exponents. Therefore,
6.41 x 10-3 ÷ 8.04 x 107 = (6.41 ÷ 8.04) x 10(-3-7) = 0.796517 x 10-10
We can express this in scientific notation by moving the decimal point one place to the left and increasing the exponent by one, giving us 7.96517 x 10-11 or approximately 7.97 x 10-11. Therefore, the answer is B.
