write 5,000,000 in scientific notation.

Explanation:

Step1: Recall scientific notation form

Scientific notation is in the form ( a \times 10^n ), where ( 1 \leq |a| < 10 ) and ( n ) is an integer.

Step2: Determine ( a ) and ( n ) for 5,000,000

For 5,000,000, we move the decimal point 6 places to the left to get ( a = 5 ) (since ( 5 ) is between 1 and 10). The number of places we moved the decimal is ( n = 6 ). So in scientific notation, it is ( 5 \times 10^6 ).

Answer:

( 5 \times 10^6 )
