sqrt(150)+sqrt(40)=sqrt(2)(5sqrt(3)+2sqrt(5))=sqrt(10(19+4sqrt(15)))

Explanation:

Hmm. Not sure if this is what you want, but you could write this as a single, NESTED radical.

sqrt(150)+sqrt(40)=sqrt(5^2(3)(2))+sqrt(2^2(5)(2))

=5sqrt(3)sqrt(2)+2sqrt(5)sqrt(2)

=sqrt(2)(5sqrt(3)+2sqrt(5))

=sqrt(2)sqrt((5sqrt(3)+2sqrt(5))^2)

=sqrt(2)sqrt(95+20sqrt(15))

=sqrt(2)sqrt(5(19+4sqrt(15)))

=sqrt(10(19+4sqrt(15)))
