Question

Express your answer in scientific notation:

7.9 times 10 to the 7th power plus 6.5 times 10 to the 6th power

Answer 1

Answer:
`7.9x10^7+6.5x10^6`

Answer 2

8.55 x 10^7

Explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
