Hey there!
3.9 times 10 to the seventh power is equivalent to the equation 3.9 × [tex]10^{7}[/tex]
The seventh power indicates the amount of times the decimal moves to the right of 3.9, so that expression would be equivalent to 39,000,000.
Hope this helps!
10^7= 10x10x10x10x10x10x10 which will equal 10,000,000
3.9 x 10,000,000= 39,000,000
39,000,000 will be your answer
