I am currently studying engineering level 3 NVQ and have been having problems with logarithms, the problems I have been given I don't understand these are:
Use laws of logarithms methods to simplify and evaluate the equation given:
Simplify 5^{n} = 7 x 2^{n}, rearrange and make n the subject
also another problem is
Simplify θ = 250 x e^{-0.05 x t }and make t the subject
and continuing from that:
what is the value of t when θ = 195^{◦}C
Thanks in advance
