### Grade 6 - Mathematics12.17 Negative Exponents

 Negative exponents mean that instead of multiplying that many of the base numbers together, you divide them. For instance, 5^2 = 5*5; on the other hand, 5^-2 = (1/5)*(1/5). In other words, if the exponent of a base is negative, it is equivalent to the positive exponent of the reciprocal of the base. Examples: a-2 = 1/(a2) = 1/(axa) = 1/a2 3-3 = 1/(33) = 1/(3x3x3) = 1/27 3-2 = 1/(32) = 1/(3x3) = 1/9 5-3 = 1/(53) = 1/(5x5x5) = 1/125 -2-2 = -1/(22) = -1/(2x2) = -1/4 (-2)-2 = 1/(-2)2 = 1/(-2x-2) = 1/4 -2-3 = -1/(23) = -1/(2x2x2) = -1/8 (-2)-3 = 1/(-2)3 = 1/(-2x-2x-2) = 1/-8 = -1/8 Directions: Answer the following negative exponent questions.
