I need to make corrections to my answers and are they right....?
7√100/√500 =
= 7*10*10*sqrt(5)
= 700sqrt(5)
=======================
4/√21 = 4√21
OK
=======================
√(400/5)
= sqrt(80)
= sqrt(16)*sqrt(5)
= 4*sqrt(5)
------------------
√(10/81)
=sqrt(10)/9
------------------
-3√(180h^4)
= -3*sqrt(36h^2)*sqrt(5)
= -3*6h*sqrt(5)
= -18h*sqrt(5)
===================
√144 = 12
OK
=========================
Cheers,
