u=log (en base 5) 0.04
u=log(5,0.04)
u=log%285%2C0.04%29

Choosing "common logs", base 10

Formula for Change of Base:
log%285%2C0.04%29=log%2810%2C0.04%29%2Flog%2810%2C5%29

log%2810%2C%284%2A10%28-2%29%29%29%2Flog%2810%2C5%29

%28log%2810%2C4%29%2Blog%2810%2C10%5E%28-2%29%29%29%2Flog%2810%2C5%29

Use table of common logs or scientific calculator
%280.60206-2%29%2F0.69897
highlight%28u=-2%29
