Answer:
4.25 x 105
Step-by-step explanation:
Why is 425,000 written as 4.25 x 105 in scientific notation?
-The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation:a x 10b
Follow the steps below to see how 425,000 is written in scientific notation.
-Step 1
To find a, take the number and move a decimal place to the right one position.
• Original Number: 425,000
• New Number: 4.25000
-Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 4 . 2 5 0 0 0
Decimal Count: 1 2 3 4 5
There are 5 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 = 4.25 (Please notice any zeroes on the end have been removed)
b = 5
Now the whole thing:
=4.25 x 105
-Step 4
Check your work:
105 = 100,000 x 4.25 = 425,000
hope it helps^^
