Answer :
Final answer:
591,000 can be expressed in scientific notation as 5.91 x 10⁵. We moved the decimal five places to the left to have only one digit before the decimal, making 5, hence the number 5 in the exponent.
Explanation:
The expression of 591,000 in scientific notation can be determined by moving the decimal point to the left until there is only one non-zero digit to the left of the decimal. From 591,000, the decimal point has to be moved five places to the left to get 5.91. Now, to remember how many places we moved the decimal, this number becomes the exponent on the 10. Hence, 591,000 can be expressed in scientific notation as 5.91 x 10⁵.
