Question

Classify each expression as rational or irrational

Answer 1

We have:

• 
  `√(6)* 0 = 0`, which is rational, since it's an integer
• 
  `\pi/\pi = 1`, which is rational, since it's an integer.
• 
  `10\pi-7\pi=(10-7)\pi=3\pi` which is irrational, because it's the product of an integer and an irrational
• 
  `√(49)+(1)/(3)=7+(1)/(3)` which is rational, because it's the sum of an integer and a rational.
