Solve each equation by writing each side with the same base and then setting the exponents equal to each other. (Example: 16 =4' is a way to write 16 as a base 4. Always go to a lower number) NO CALCULATOR!! (I did a few for you for examples) 21) 5- 52+2 (bases are alike) 3n = an+7 22) 53 - 25 - 2 r 1 = 2 (5)* = (5) 23) 23 - 2x - 4 6-4x 2 4 24) 31= = 1 3-2X = 2 (1) -2x = - 7 74 1 - -2 25) 2" -" = 16 16 is sameas 2 26) 4-1 2" = 27 2 - 1 = 4 - M = 2 1= - 2 27) 643- =82 28) 36-20-2 63 36 is 62 62 ( - 2m -2) 3 = 6 2 ( - 2 1 - 2 ) = 3 - 4n - 4 = 3 - Hm = 7 29) 165-3- 43 30) 16 - 64
