I like the way you go through the logarithm properties and explain step by step. Keep up the good work!!!

[@MasterTMathsClass]

Glad you like them!

Interesting 🎉

Glad you think so!

4^(x-2)=15 2^(2x-4)=3•5 2x-4=log_2(3•5) 2x-4=log_2(3)+log_2(5) 2x=4+log_2(3)+log_2(5) x=2+½log_2(3)+½log_2(5) ❤

Which rule u apply for logarithm making it as base for calculating

[@joanlester7868]

log usually refers to base 10, 'ln' refers to natural logarithm i.e. base e. They both have the same rules. Here you can use any of these but since we do not find the value of any logarithms it doesn't matter, you could use base 7 or base 56 but that would waste time and pen.😊

×=(4×4)-2=15/15=1 ×=16-2=14+1=15 15=15... ×=(4×2)=8 15-8=7 8+7=15 15=15....
