01. Determine o valor das expresses:a) y=log 37 . log 73 . log 511 . log 115b) y=log 23 . log 34 . log 45 . log 56c) y=log 23 . log 818d) y=log 32 . log 103 . log 210e) y=log 53 . log 274 . log 210f) y=log 53 . log 8125

02. Determine o domnio das funesa) y=log (x3)3b) y=log (x 29)2c) y=log (x 24)(x2)d) y=log (2x+7)(x2)

03. Resolva os sistemas

a) x+ y=10

log x4 +log y4 =2

b) x . y=1

log x3 log y3 =2

c) x+2y=15

log x10 log y10 =log 310

d) x+ y=20

log x10 +log y10 =2

e) 4x y=16

log x10 log y10 =log 210
