Explanation:

Response
Problem 1: Classify $\pi$

Step1: Recall rational/irrational def

A rational number can be expressed as $\frac{p}{q}$ ($p,q$ integers, $q
eq0$), irrational cannot. $\pi$ is non - repeating, non - terminating, so irrational.

Step1: Identify number type

$2.878787\cdots$ is a repeating decimal. Repeating decimals can be written as a fraction (e.g., let $x = 2.8787\cdots$, $100x=287.8787\cdots$, $99x = 285$, $x=\frac{285}{99}$), so it's rational.

Step1: Simplify the square root

$\sqrt{36}=6$, and $6=\frac{6}{1}$, which is a rational number (integer, hence rational).

Answer:

Irrational: X (Rational: no X)

Problem 2: Classify $2.878787\cdots$
