Answer 1

1)(3v7.5)^2 - v3 * v0.12 + v2/v8 = 9*7.5 - v0.36 + v1/4 = 67.5 - 0.6 + 0.5 = 67.4
2)a/4 v(8a) = v(8a^3/16) = v(a^3/2)
3)v48 + v75 - v108 = 4v3 + 5v3 - 6v3 = 9v3 - 6v3 = 3v3
4)(4 - v3)^2 - (2v5 - 1)(2v5 + 1) = 19 - 8v3 - 10 + 1 = 10 - 8v3 
5)(v(15x) - v5)/(3x -1) = v5(v(3x) - 1)/(v(3x) - 1)(v(3x) + 1) = v5/(v(3x) + 1)
