^ = pangkat

log x = p

(2 . log x - 1) . 1/(ˣlog 10) = log 10
(2 . log x - 1) . log x = 1
2 . log² x - log x - 1 = 0
2p² - p - 1 = 0
(2p + 1) (p - 1) = 0
2p + 1 = 0
2p = -1
p = -1/2
log x = -1/2
x = 10^(-1/2)
x = 1/√10
x = (1/10) √10

p - 1 = 0
p = 1
log x = 1
x = 10¹
x = 10

x1 . x2
= (1/10) √10 . 10
= √10
