    1.274*10^25 is the correct answer. This is a shorthand way writing out this VERY big number. The answer is approximately 12,740,000,000,000,000,000,000,000. To avoid writing all those 0's it is customary to use the shorthand notation. Your calculator may have given you an answer like "1.274174347624957e25". Look out for the 'e25' at the end of that line of digits. It means "move the decimal point to the right 25 times". Another way to move the decimal point right 25 times is by multiplying the number by 10^25. This notation is read as, "10 to the power of 25." Good Luck!
