 We can verify that $F(6) = 5$, $F(8) = 9$, $F(20) = 450$ and $F(1000) ≈ 8.8521816557e\\,21$.
 
-Find $F({10}^{18})$. Give as your answer as a string in its scientific notation rounded to ten digits after the decimal point. When giving your answer, use a lowercase `e` to separate mantissa and exponent. E.g. if the answer is $112\\,233\\,445\\,566\\,778\\,899$ then the answer format would be `1.1223344557e17`.

 # --hints--
 
 `permutationOf3SmoothNumbers()` should return a string.
 
 ```js
-assert.strictEqual(typeof permutationOf3SmoothNumbers() === 'string');
+assert.strictEqual(typeof permutationOf3SmoothNumbers(), 'string');
 ```
 
 `permutationOf3SmoothNumbers()` should return the string `5.5350769703e1512`.
