If Log2 x - 5 Log x + 6 = 0, then what would the value / values of x be?
Read Solution (Total 3)
-
- log(2x)-5log(x)+6=0 (given)
log(2x)-log(x^5)=-6
log(2x/x^5)=-6 [since log(a)-log(b)=log(a/b)]
apply anti log
2/(x^4)=e^-6
2/(x^4)=2.4788*10^-3
x^4=806.85
x=5.3296

- log2 x - 5 log x + 6 = 0
(log x) / (log 2) - 5 log x = -6
(log x) (1/log 2 - 5) = -6
log x = -6 / (1/log 2 - 5)
log(x) = -6 / (3.3219 - 5)
log(x) = 3.575521
x = 10^(3.575521)
x ≈ 3763. - 12 years agoHelpfull: Yes(6) No(10)
