<u>Answer</u>

√7 × √5

√3 × √2


<u>Explanation</u>

√9*√16   = 3 × 4

              = 12

             = 12/1      ⇒ It is a rational answer.

√7*√5  = √(7×5)

            = √35

           = 5.916079783.... ⇒ Irrational

√3*√2  = √(3×2)

           = √6

            = 2.449489743...  ⇒  Irrational

4√2*√2 = 4 × √(2×2)

              = 4 × √4

              = 4 × 2

              = 8

              = 8/1   ⇒  It is rational

The expressions that would give irrational answers are: √7*√5  and√3*√2
