your notation makes no sense
on the right side you have
there is no such notation.
The expression on the left is even worse.
this is exactly what my homework sheet says. this is not teacher made, it's from the book. 2log(base2)^10 = log(base2)^10^2 = log(base2)^100
In this and most forums the ^ is used as an exponent indicator
e.g. 2^3 = 23
looking at your last line in the previous reply, I will assume that by
2log(base2)^10 = log(base2)^10^2 = log(base2)^100 you really meant :
2log(base2)10 = log(base2)10^2 = log(base2)100
so your question of
log(base2)^(x-3)log(base2)^5 = 2log(base2)^10 is really
log(base2)(x-3)log(base2)5 = 2log(base2)10 or
log2(x-3)log25 = 2log2100
divide by log25
log2(x-3) = log2100/log25
log2(x-3) = log100/log5 = 2.861353
so x-3 = 2^2.861353
x-3 = 7.26697
x = 10.26697
