Answer:

54

Explanation:

using the rule of radicals


√(ab) =
√(a) ×
√(b) and
√(a) ×
√(a) = a , then


√(6) × 3
√(54)

=
√(6) × 3 ×
√(9(6))

=
√(6) × 3 ×
√(9) ×
√(6)

=
√(6) ×
√(6) × 3 × 3

= 6 × 9

= 54

{ \qquad\qquad\huge\underline{\boxed{\sf Answer}}}

Here's the solution ~


\qquad \sf  \dashrightarrow \: √(6) * 3 √(54)


\qquad \sf  \dashrightarrow \: √(2 * 3) * \sqrt{2 * {3}^(3) }


\qquad \sf  \dashrightarrow \: \sqrt{ {2}^(2) * {3}^(4) }


\qquad \sf  \dashrightarrow \:2 * {3}^(2)


\qquad \sf  \dashrightarrow \:2 * 9


\qquad \sf  \dashrightarrow \:18
