Question

Drag and drop each number into the correct box to tell wheter it is rational or irrational

Answer 1

Rational:

The product of sqrt(2) and sqrt(50)

The product of sqrt(2/pi) and sqrt(50pi)

The product of sqrt(2) and sqrt(9/2)

C= 2pi*r evaluated at r=pi^-1

A-pi*r^2 evaluated at r=pi^-1/2

Irrational:

C=2pi*r evaluated at r=1

The product of sqrt(2) and sqrt(25)

Explanation:

Answer 2

Haven't you tried to answer these yourself?

Let me give you 2 examples:

First: The product of sqrt(2) and sqrt(25) is 5sqrt(2), which is irrational because sqrt(2) is irrational.

Second: 2pi*r evaluated at pi^(-1) is rational because pi/pi = 1 and 2 itself is rational.
