x= 10^(1.8) ~~63.096x=101.863.096

Explanation:

log xlogx means log_10 xlog10x

By definition
color(white)("XXX")log_b p = qXXXlogbp=q
is equivalent to
color(white)("XXX")p=b^qXXXp=bq

Therefore
color(white)("XXX")log_10 x = 1.8XXXlog10x=1.8
is equivalent to
color(white)("XXX")x= 10^(1.8)XXXx=101.8
(which can be evaluated using a calculator as approximately 63.09663.096)
