(2.logx-1)1/^xlog10=log10 Maka x1.x2=....

(2.logx-1). 1/xlog10 = log10
(2.logx - 1). logx = 1
misalkan
logx = a
(2a-1).a = 1
2a^2 -a = 1
2a^2 - a - 1 = 0

cara 1
----------

(2a + 1)(a- 1) = 0
a = -1/2 atau a = 1

a = -1/2
logx = -1/2
x = 10^(-1/2) = 1/akar10

a = 1
logx = 1
x = 10^1 = 10

maka x1.x2 = 10^(-1/2) . 10 = 10^1/2 = akar10

cara 2
---------

2a^2 - a - 1 = 0

a1+a2 = 1/2
logx1 + logx2 = 1/2
logx1.x2 = 1/2
x1.x2 = 10^(1/2) = akar10
