Answer:
No. The 2nd machine makes more!
Step-by-step explanation:
So we want to know whether the two machines are making copies at the same rate. So let's use a ratio.
Machine 1 5 copies: 8 seconds
Machine 2 16 copies: 24 seconds
5:8 and 16:24
try and make them the same.
5:8
16:24
8*3=24
5*3=15
15=16?
no. So the two machines work at different paces.
Number 1 and I think 4 not sure but try those .
This is essentially a rule in the unit of radicals, where n✔️X^m = X^m/n. If the value of m is equal to n, as in 2✔️3^2 it would simply be 3^2/2 which is nothing but 3^1 = 3. Basically, the m value can be greater than n and or less than n, but if it is equal the m and n values cancel out.
