If Log2 x - 5 Log x + 6 = 0, then what would the value / values of x be?
Read Solution (Total 1)
-
- log2x-5logx+6=0
log2+logx-logx-4logx+6=0
log2-4logx +6=0
log2-4logx+log10^6=0
log2+log10^6=logx^4
logx^4=log(2*(10^6))
remove log
x^4=2*(10^6)
therefore
x=root of (root of(2*10^6))
x=21.147 - 9 years agoHelpfull: Yes(3) No(2)
