v(18a^2)*4v(3a^2)

Question

Answer 1

The square root of a number squared (for example, 3*3) is the original number (for example, 3).

 

To simplify this expression, find all the squares and take them outside the radical.

 

  √(18a^2) * 4√(3a^2)

  √(3*3*2*a*a) * 4√(3*a*a)          [just expand everything]

  3a√(2) * 4a√(3)                     [take squares outside radical]

   12a²*√2*√3                         [collect and rearrange terms]

     12a²√6                               [combine terms]

 

Answer 2

√(18a²)*4√(3a²)

a√18*4a√3

4a²√54

4a²√9*6

4a²*3√6

12a²√6
