p^3 ÷ p^2 = p^(3-2) = p^1 = p
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)
