What is 19.212 x 10 to the power of 2

1921.2

Step-by-step explanation:

Heres a way of showing you how to do it. This is not how to solve it to YOUR problem. These are examples!!

1) Multiply the coefficients

2) Add the exponents (base 10 remains)

Example 1: (3 x 104)(2x 105) = 6 x 109

What happens if the coefficient is more than 10 when using scientific notation?

Example 2: (5 x 10 3) (6x 103) = 30. x 106

While the value is correct it is not correctly written in scientific notation, since the coefficient is not between 1 and 10. We then must move the decimal point over to the left until the coefficient is between 1 and 10. For each place we move the decimal over the exponent will be raised 1 power of ten.

30.x106 = 3.0 x 107 in scientific notation.

Example 3:

(2.2 x 10 4)(7.1x 10 5) = 15.62 x 10 9 = 1.562 x 10 10

Example 4:

(7 x 104)(5 x 106)(3 x 102) = 105. x 10 12 --now the decimal must be moved two places over and the exponent is raised by 2. Therefore the value in scientific notation is: 1.05 x 10 14

the answer is a
