when you move the decimal left, increase the exponent.

when you move the decimal right, decrease the exponent.

(you can easily understand this by telling yourself, did i make the number smaller or bigger? if you’ve made it smaller, make the exponent bigger. vise versa.)

1) 9,040,000,000

9.04 x 10 ^ 9

2) 0.02

2 x 10 ^ -2 or 2.00 x 10 ^ -2

3) 9.3 million ( 9, 300, 000 )

9.3 x 10 ^ 6

4) 21,700

2.17 x 10 ^ 4

5) 0.00325

3.25 x 10 ^ – 3

6) 8,003,000

8.003 x 10 ^ 6

7) 0.00092

9.2 x 10 ^ – 4

8) 0.0156

1.56 x 10 ^ – 2

ie: 9,040,000,000 = 9.04 x 10 to the 9th power (how many spaces you moved it)

for the really small numbers move the decimal point to the right so that there is only one digit on the left

ie: 0.02 = 2.0 x 10 to the 2nd power

i would guess but im only in middle school so your out of luck…

I would totally guess but if its ur grades then no
