Question

How would you solve the equation log4x=2.5? Totally blanked on this.

Answer 1

if this is
\[\log_4(x)=2.5\] then
\[x=4^{2.5}\]

Answer 2

It's not, it's just log4x.

Answer 3

if it is
\[\log(4x)=2.5\] then you have to do something else

Answer 4

ok then in that case you have
\[4x=10^{2.5}\] and you need a calculator

Answer 5

\[x=10^{2.5}\div4\] whatever that is

Answer 6
