log²x + log x² = log2² - 1
{ log x }² + 2log x +1 = { log 2 }²
let log x = Q
Q² + 2Q + 1 = { log 2 }²
( Q + 1)² = { log 2 }²
Q + 1 = ± log 2
Q = -1 ± log 2
log x = - log 10 ± log 2
log x = -log10 - log 2 , -log 10 + log2
logx = -log 20 , log (2/10 )
log x = log (1/20 ) , log ( 1/5)
x = 1/20 , 1/5
{ log x }² + 2log x +1 = { log 2 }²
let log x = Q
Q² + 2Q + 1 = { log 2 }²
( Q + 1)² = { log 2 }²
Q + 1 = ± log 2
Q = -1 ± log 2
log x = - log 10 ± log 2
log x = -log10 - log 2 , -log 10 + log2
logx = -log 20 , log (2/10 )
log x = log (1/20 ) , log ( 1/5)
x = 1/20 , 1/5
