The number is written as
[tex] 93 \times 10^6 [/tex]
To evaluate the power of ten, just remember that 10 to the power of n is a one followed by n zeroes, so ten to the sixth power is a one followed by six zeroes:
[tex] 10^6=1000000 [/tex]
So, the number is
[tex] 93 \times 1000000 [/tex]
When you multiply a number by a power of ten, you simply add the same number of zeroes after the number. So, in this case, you only need to add six zeroes after 93:
[tex] 93 \times 1000000 = 93000000[/tex]
which is 93 millions.
