Question

3(4 log t^2)

Would it be logt^8 or are you not allowed to do that?

And

logy-4(logr+2logt)

in the first one, what happened to the 3?
my answer is log t^24

in the second...
=logy - 4(logr + logt^2)
=logy - 4log rt^2
= logy - log r^4t^8
=log(y/(r²t⁸))

correction, last line

log(y/(r4t8))
