(a) 4.00^{0.360} = 1.65 (3 sig. fig)

(b) (7.10)^{log3.20} = 7.10^{0.505} = 2.69 (3 sig. fig.)

(c) (log 2.40)^{log 0.930} = 0.380^{-0.0315} = 1.031 (3 sig. fig.)

If you don't have a y^{x} key, they can be solved by taking logarithms:

(a) log (4.00^{0.360}) = 0.360 log 4.00 = 0.360X0.602 = 0.2167

antilog (0.2167) = 1.65

(b) (7.10)^{log3.20} = 7.10^{0.505}

log (7.10^{0.505}) = 0.505 log 7.10 = 0.505X0.851 = 0.4299

antilog (0.4299) = 2.69

(c) (log 2.40)^{log 0.930} = 0.380^{-0.0315}

log (0.380^{-0.0315}) = -0.0315 log 0.380 = -0.0315(-0.4202) = 0.01324

antilog (0.01324) = 1.03
