# What is a Prime Number?
A prime number is an integer that has only two factors — 1 and itself. It can be divided evenly only by 1 and by itself, and must be greater than 1. For example, 3 is a prime number because it cannot be divided evenly by any number except for 1 and 3.

To solve this, first find the power of 7 that equals 2401 by guessing values of y in the equation 7^y = 2401.
Testing values of y:

To determine if a number is happy, square each of its digits, add the results, and repeat the process. If the final result is 1, the number is considered happy.
For example, consider the number 19:

8^2 + 2^2 = 68
6^2 + 8^2 = 100
1^2 + 0^2 + 0^2 = 1

# Worksheet: First-Order Linear Differential Equations
This worksheet practices solving linear first-order differential equations.
**Q1:** Solve the differential equation dy/dx = 2x - 3y.
- A: y = (2/3)x - (1/3)
- B: y = (2/3)x + (1/3)
- C: y = (3/2)x - (1/2)
- D: y = (3/2)x + (1/2)
- E: y = (1/2)x - (1/2)
