Question

qual o valor de cada uma das expressões? b) = log 1/4^4+ log 4^1/4

Answer 1

log 1/4^4+ log 4^1/4

log(2^-2)^4 + log(2^2)^1/4

log 2^- 8 + log 2^2/4

- 8log2 + 2 log2
               4

- 32log + 2log2
            4

- 20log2  ==> - 5log2
      4

Answer 2

log 1/4^4+log 4^1/4=
4.log 1/4+1/4.log 4=
4. (log 1-log 4)+1/4.log 4
log 4=log2^2=2.log2=2.0,301=0,602
4. (0-0,602)+1/4.0,602
-2,4080+0,1505=
= -2,2575
