Elena is correct. Because the number 28 is smaller and above the number two, that means it is the exponent. The exponent, or the power, tells you how many times you multiply the number by itself. For example 2 to the 3rd power or 2 with a small 3 above it would be 2 x 2 x 2 which is 8 instead of 2 x 3 which is 6. I hope this helped you and good luck!
