Question

Write the product in scientific notation. (8.9 x 105) *(5.2 x 10-2)

A) 46.28 x 10^3
B) 46.28 x 10^2
C) 462.8 x 10^4
D) 4.628 x 10^3

Answer 1

To write the product (8.9 x 105) * (5.2 x 10-2) in scientific notation, multiply the coefficients and add the exponents. The product is 46.28 x 10^3.

Step-by-step explanation:

To write the product (8.9 x 105) * (5.2 x 10-2) in scientific notation, we multiply the coefficients and add the exponents of the powers of 10. The product of 8.9 and 5.2 is 46.28. The exponent of 10 in scientific notation is the sum of the exponents, which in this case is 5 + (-2) = 3. Therefore, the product is 46.28 x 103.

The correct answer is A) 46.28 x 10^3
