Which of the following is a perfect square expression? (More than one correct answer)

Complete the following expression to make a perfect square: $$9x^2$$ ​ (a)   $$+144$$

Factorise fully: $$x^2-10xy+25y^2$$

Factorise fully: $$24x^2y+3x^4+48y^2$$

Solve for x by taking the square root on both sides: $$11+x^2=4x^2+5$$

Solve for x and give the answer in simplest surd form: $$\frac{x^2}{16}+3=27$$

Solve for x and give the answer in simplest surd form: $$3\left(x-5\right)^2+7=43$$

$$\sqrt[]{12}$$ is a/an​ (a)   number. ​

$$\sqrt[]{121}$$ is a ​ (a)   number.

$$\frac{3\pm\sqrt[]{21}}{6}$$ is a​ (a)   number.
