c) \(=\left(5a-\dfrac{1}{3}\right)^2\)

d) \(=\left(y-\dfrac{1}{3}\right)^2\)

e) \(=\left(2x-y+1\right)^2\)

f) \(=\left(2x-4y\right)^2+2\left(2x-4y\right)+1=\left(2x-4y+1\right)^2\)

g) \(=\left(2xy^2-3\right)^2\)

Answer 2

\(c,=\left(5a-\dfrac{1}{3}\right)^2\\ d,=\left(y^4-\dfrac{1}{3}\right)^2\\ e,=\left(2x-y+1\right)^2\\ f,=\left(2x-4y\right)^2+4\left(x-2y\right)+1=\left(2x-4y+1\right)\\ g,=\left(2xy^2-3\right)^2\)
