There are about 208,000,000,000 different 8-letter passwords that can be formed using a 26-letter alphabet.

Express this number using scientific notation.
0 2.08 x 1011
O 208 10
O 20.8 x 1010
0 0.208 x 1012

2.08 x 10^11

Step-by-step explanation:

To put a number into scientific notation you move the decimal to the spot right after the first digit. To figure out what the power is you count how many digits you moved it past in order to get to the spot you want it (right after the first digit; in this case the 2)

So in this case you would move the decimal from the end of the number backwards past 9 zeros, the 8, and another zero, which is a total of 11 digits.

From there you take the number with the new decimal place and multiply by 10 to the power of the number you counted earlier, which for this example is 11

So the final answer is 2.08 x 10^11
