PLEASE HELP ASAP Which expressions simplify to an irrational answer? (Select each correct answer.) √9*√16√7*√5√3*√24√2*√2

Answer√7 × √5 √3 × √2
Explanation√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...  ⇒  Irrational4√2*√2 = 4 × √(2×2)               = 4 × √4               = 4 × 2               = 8               = 8/1   ⇒  It is rationalThe expressions that would give irrational answers are: √7*√5  and√3*√2
