        75000000


        7.5000000 x 10^7


        To find the exponent count the number of places from the decimal to the end of the number.


        Put the decimal after the first digit and drop the zeroes


        7.5 x 10^7


        <var style="font-family: 'Times New Roman'; font-size: medium;">The first number is called the coefficient</var>. It must be greater than or equal to 1 and less than 10.


        The second number is called the base . It must always be 10 in scientific notation. The base number 10 is always written in exponent form. In the number 7.5 x 107 the number 7 is referred to as the exponent or power of ten.


        Answer:  7.5 x 10^7
