Hello there Math master, (I wonder if I could become one later...)
I have this several questions in which I could not find the answer..I'm stuck.
If and , find the value of 10^3m-n
Now I have tried randomly and find out that m = 1/5, but I do not know the proper way how to find m and n respectively. The book said that we need to find the common factor of 10 and 2, but so far I could not find any because the number seems very weird...
There's also this another question which is nearly the same:
Given that and , find the value of 3^2x-3y, giving your answer in fraction.
Thank you for your kind help.
