Question

Match each number in scientific notation with the number written in standard form. A. 6.82×10^7 0.00000682 B. 6.82×10^-6 6,820,000 C. 6.82×10^6 68,200,000

Answer 1

`6.82x10^(7)` = 68, 200, 000.

`6.82x10^(-6)` = 0.00000682

Explanation:

first you need to look to the exponent signal, if it is positive, will be greater tha 0. If it is negative will be smaller than zero.

7 is a positive number, just need to move the decimal point 7 places to the right, add the zeros as needed.

-6 is a negative number, then you move six places to the left. Make sure you count after the decimal point six digits, in this case include five zeros.
