Answer:4:5xn
Step-by-step explanation:
You can use any ratio just times 4:5 by any number then you'll get a ratio equivalent to 4:5
Answer:
log(32/125)
=log32 - log125 [log(x/y)=log(x) - log(y)]
=log(2)^2 - log(5)^3
=2log2-3log5 [log(x)^p=p log x]
=2a-3b
0.71 x 22 is the expression that works, because 1 AUD = 0.71USD.
