Question

X= log 3 5 * log 4 27 * log 3 sqrt 2 25

Answer 1

ok. what, you want a simpler numeric value for x?

All those spaces are confusing, but if you mean

log_3(5) * log_4(27) * log_3(√225)
that is kinda weird. I suspect a typo. So, using base 3 logs all the way, I get

log5*log27*log15
=4log3*2log5

since log_3(3) = 1, that is just

2log5 or log25

Most calculators don't have a log_3 button, so change the base to 10 or e (does not matter which):

log_3(25) = log25/log3
