WebbWhat are powers/indices? Powers of a number is when that number is multiplied by itself repeatedly. 5 1 means 5. 5 2 means 5 × 5. 5 3 means 5 × 5 × 5. Therefore the powers of 5 are 5, 25, 125, etc. The big number on the bottom is sometimes called the base number. The small number that is raised is called the index or the exponent.

WebbYou should think about the "before" quantity (even though it is not given in the question) Find the percentage change as a multiplier, p (the decimal equivalent of a percentage change) a percentage increase of 4% means p = 1 + 0.04 = 1.04. a percentage decrease of 5% means p = 1 - 0.05 = 0.95. Use "before" × p = "after" to write an equation.
