Need . how do i write a number in scientific notation

Calculating scientific notation for a positive integer is simple, as it always  follows this notation: a x 10^b

Follow the steps below to see how 102,800,000 is written in scientific notation.

To find a, take the number and move a decimal place to the right one position.

Now, to find b, count how many places to the right of the decimal.

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10^b

a = 1.028 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.028 x 10^8

Check your work:

108 = 100,000,000 x 1.028 = 102,800,000

Hope this helps! :)

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
