Answer:

7) 7.8*10^0

8) 3.2 * 10 ^-7

Step-by-step 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.

7.80

The coefficient must bebetween 1 and 10.

7.80x10^0

We move the decimal point 0 units or don't touch it at all.

0.00000032

3.2x10^-7

Remember that the negative exponent means the number is small and we move the decimal point to the left.

Hope it helps!
