2 squared divided by 3 squared ie 4/9 in general, (a/b)^n = a^n/b^n . In this case (2/3)^2=2^2/3^2=4/9 Check: 2/3 = .667 squared = 0.444889; 4/9 =0.44444. Near enough!
Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)

The answer is 4.
3² + 20 ÷ 2² = 9 + (20 ÷ 4) = 14.
2752 = 75625 42 = 16 32 = 9 22 = 4 75625/16 + 9 + 2 = 4737.5625
Y = 4/x^2
It is 36/6 +4 = 10
