Multiply and simplify the following products. V stands for radical. Example: (V5)2= (V5) (V5) = v(5 x 5) = 5
1. (19)
2. (V2) (13)
3. 2(12) x 3(3)

(1) 9

(2)

(3) 6()

Step-by-step explanation:

From the question,

(1) ()²

    Applyin the law of multiplication of surds

   ()²  = (

(2)  ()× () =

   Also applying the the law of multiplication of surd

   ()×() =  () ( This is an irational answer)

   ∴ ()×()  =

 (3) 2()×3()

     Also applying the law of multiplication of surds i.e Multiply surds to     surds and whole number to whole number

     = 2×3×()×()

       6×() = 6(

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
