Why 18n = 45k Implies Only Multiples of 90: A Simple Mathematical Breakdown

When solving equations involving variables, especially in algebra, understanding the chain of logic can clarify their implications. One such equation—18ₙ = 45ₖ—may seem straightforward, but unpacking it reveals deeper relationships that define specific values. Let’s explore step-by-step why this equation leads uniquely to θ = 90a, meaning only multiples of 90 are valid solutions.

The Equation: 18ₙ = 45ₖ

Understanding the Context

This notation expresses a proportional relationship between two expressions: 18 times the unknown variable n, and 45 times another unknown variable k. At first glance, the equation seems symbolic, but we can simplify it through algebraic manipulation.


Step 1: Simplify 18ₙ = 45ₖ

Although written with superscripts (often used for exponents), here n and k represent variables, so 18ₙ means 18 times n, and 45ₖ means 45 times k. Thus, the equation becomes:

18n = 45k


Step 2: Reduce the Equation

We simplify 18n = 45k by dividing both sides by the greatest common divisor of 18 and 45, which is 9:

(18n ÷ 9) = (45k ÷ 9)
2n = 5k

Final Thoughts

This reduced form reveals a direct proportional relationship between n and k. Because 2 and 5 have no common factors, n must increase in multiples of 5 and k in multiples of 2 to maintain the equality.


Step 3: Express One Variable in Terms of a Shared Parameter

From 2n = 5k, solve for n:

n = (5k) / 2

For n to be an integer, k must be even. Let k = 2a (where a is any positive integer). Substituting:

n = (5 × 2a) / 2 = 5a


Step 4: Solve for θ (or θ = 18n)

Earlier, we derived θ = 18n. Substituting n = 5a:
