Final answer:
To simplify, we apply the properties of logarithms.
Step-by-step explanation:
To simplify the expression, we can use the properties of logarithms.
a) log₅(y) - 4log₅(r)log₅(t) = log₅(y) - log₅(r´t⁴) = log₅(y/r´t⁴)
b) log₅(y/r) - 4log₅(t) = log₅(y/r) - log₅(t⁴) = log₅(y/r´t⁴)
c) log₅(y) - 2log₅(r)log₅(t) = log₅(y) - log₅(r²t²) = log₅(y/r²t²)
d) log₅(y/r) - 2log₅(t) = log₅(y/r) - log₅(t²) = log₅(y/r²t²)
