$\Large\boxed{\begin{array}{l}\tt a)~\sf z^2=16\cdot25\\\sf z=\sqrt{16\cdot25}\\\sf z=4\cdot5\\\sf z=20\\\tt b)~\sf 12^2=24y\\\sf 24y=144\\\sf y=\dfrac{144}{24}\\\\\sf y=6\\\tt c)~\sf c^2=5\cdot2\\\sf c^2=10\\\sf c=\sqrt{10}\\\sf b^2=5\cdot3\\\sf b^2=15\\\sf b=\sqrt{15}\\\sf h^2=2\cdot3\\\sf h^2=6\\\sf h=\sqrt{6}\end{array}}$

$\Large\boxed{\begin{array}{l}\tt d)~\sf y=5+3=8\\\sf x^2=8\cdot3\\\sf x^2=24\\\sf x=\sqrt{24}\\\sf x=\sqrt{2^2\cdot3}\\\sf x=2\sqrt{3}\\\\\tt e)~\sf y^2=9\cdot16\\\sf y=\sqrt{9\cdot16}\\\sf y=3\cdot4\\\sf y=12\\\sf z^2=25\cdot9\\\sf z=\sqrt{25\cdot9}\\\sf z=5\cdot3\\\sf z=15\\\sf x^2=25\cdot16\\\sf x=\sqrt{25\cdot16}\\\sf x=5\cdot4\\\sf x=20\end{array}}$
