What is 52,427 equal in scientific notation

Ivanshal [37]

Answer: 5.2427 x $10^{4}$

Explanation: To write a number in scientific notation, first write a decimal point in the number so there is only 1 digit to the left of the decimal point.

So here, we have 5.2427 and notice that there is only 1 digit to the left of the decimal point. Next, we count the number of places the decimal point would need to move to get back to the original number 52,427.

Since we would need to move the decimal point 4 places to the right, we have an exponent of positive 4.

Now, Scientific notation is always expressed as a number times a power of 10. So in this case we have 5.2427 x $10^{4}$ .

So 52,427 can be written in scientific notation as 5.2427 x $10^{4}$ .
