(2 points)

4+9

pi * 5

3 overline 45 * 1.2

sqrt(16) * sqrt(4)

sqrt(7) * sqrt(2)

1 answer

- 4 + 9 = 13 (rational sum)
- π * 5 = 5π (irrational product)
- 3.45 * 1.2 = 4.14 (rational product)
- sqrt(16) * sqrt(4) = 4 * 2 = 8 (rational product)
- sqrt(7) * sqrt(2) = sqrt(14) (irrational product)

The expressions 4 + 9, 3.45 * 1.2, and sqrt(16) * sqrt(4) result in a sum or a product that is rational.
