Is the product of 4/7 and radical 16 a rational or irrational number? Explain.
Since √16 = 4, which is rational,
a product of a rational x a rational is rational.
(4/7)√16
= (4/7)(4) = 16/7 , which is rational
I am sure Henry meant to say rational.
radical 16 ... √16 ... equals ±4 ... a rational number
the product of two rational numbers is rational
