Each of the following functions can be written asb^kx, wherebis equal to 2, 3, or 5 andkis some number.

Enter the appropriate values ofbandkin each case.

1. f(x) = 27^x. b= ?k= ?
2. f(x) = 3^3x/3^4x b= ? k= ?
3. f(x) = 16^2x x 32^-6x b= ? k= ?

HINT: You might find it useful to write down the values of the first four or five powers of 2, 3 and 5.
