a)

$= \sqrt{150}$

$= \sqrt{5 {}^{2} \: . \: 6 }$

$= \sqrt{5 {}^{2} } \sqrt{6}$

$\boxed { = 5 \sqrt{6} }$

b)

$= \sqrt{512}$

$= \sqrt{16 {}^{2} \: . \: 2}$

$= \sqrt{16 {}^{2} } \sqrt{2}$

$\boxed { = 16 \sqrt{2} }$

c)

$= \sqrt{720}$

$= \sqrt{12 {}^{2} \: . \: 5 }$

$= \sqrt{12 {}^{2} } \sqrt{5}$

$\boxed { = 12 \sqrt{5} }$

d)

$= \sqrt{2187}$

$= \sqrt{27 {}^{2} \: . \: 3}$

$= \sqrt{27 {}^{2} } \sqrt{3}$
