Problem

Convert 6,200,000 into scientific notation.

2

Step

Given number

6,200,000

3

Step

Move to the decimal to the left in 6 places.So it is positioned to the right of the leftmost non-zero digits

6.2

4

Hint

Remove all the zeroes and multiply the number by 10. Now the number has become = 6.2.

5

Step

Since the number is greater than 10 and the decimal is moved to left, therefore, we use here a positive exponent.

6200000

⇒ \$6.2 \times (10)^6\$

6

Solution

So, in scientific notation, 6,200,000 is written as \$6.2 \times (10)^6\$.
