49-9=40

5:44 (x+y) (x-y)=20x2 has integer solutions, 11 and 9.

but when x and y got substituted, u is not an integer

[@MorgKev]

1) You didn’t say integer solutions only. 2) because m is an integer doesn’t force sqrt(m) to be an integer and hence u didn’t have to be an integer. I sure you started with your solution and worked back to create your question… you should ask your question with all your little bits of extra information required to get to the solution you want.

No such thing as a Stanford university admission test. And if there was, this question would never qualify as it is way too easy.

To verify, you don't equate the LHS to 40 ,you just world out what the LHS is and if it comes to 40 the solution(s) are verified

Square root of m can be written m^1/2 not m/2.

let u^2=(V7)^(Vm) , & v^2=(V3)^(Vm) , I count on one occasion , u^2-v^2=10*4 , (u+v)(u-v)=10*4 , let u+v=10 & u-v=4 , u+v+u-v=14 , 2u=14 , u=7 , u^2=49 , (V7)^(Vm)=49 , Vm=2*log7/((log7)/2) , Vm=4 , m=16 , test , (V7)^(V16)-(V3)^(V16)=(V7)^4-(V3)^4 , 49-9=40 , OK , solu , m=16 ,

m=16 by inspection. No algebra needed. At this level, should it even exist, it’s obvious 49-9 is required.

This can be proven in 30 seconds so why take 11 minutes
