Question

express the following number in scientific notation 480000000 please ans step by step ​

Answer 1

Step-by-step explanation:

Step 1

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

Original Number: 480,000,000

New Number: 4.80000000

Step 2

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

New Number: 4 . 8 0 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.

Remember, the notation is: a x 10b

a = 4.8 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

4.8 x 108

Step 4

Check your work:

108 = 100,000,000 x 4.8 = 480,000,000

if my answer is correct give me brainliest mark
