when they say a number is "to a power" like "5 to the second power" its the same thing as 52 read "5 squared" to solve this all you have to do is 5x5=25. if you have "3 to the fourth power" you would do 34 which is the same as 3x3x3x3=81.

3^(-4) = (1/3)^4 = 1/81
it's the same as 1 over the same number to a positive power. 2 to the power -3 = 1/ 2 cubed = 1/8
2 minus 5 is -3, sooo your answer should be negative 3 over 7.
