Question

write the numbers in scientific notation 408000000​

Answer 1

Step-by-step explanation:

408000000=4.08×10^8

Answer 2

Answer:

Step 1

To find a, take the number and move a decimal place to the right one position.  

Original Number: 408,000,000

New Number: 4.08000000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 4 . 0 8 0 0 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.   The notation is: a x 10^b

a = 4.08

b = 8

Now: 4.08 x 10^8

10^8 = 100,000,000 x 4.08 = 408,000,000
