# --description--
|
||
|
|
||
|
The number 512 is interesting because it is equal to the sum of its digits raised to some power: 5 + 1 + 2 = 8, and 83 = 512. Another example of a number with this property is 614656 = 284.
|
||
|
|
||
|
We shall define an to be the nth term of this sequence and insist that a number must contain at least two digits to have a sum.
|
||
|
|
||
|
You are given that a2 = 512 and a10 = 614656.
|
||
|
|
||
|
Find a30.

`euler119()` should return 248155780267521.
|
||
|
|
||
|
```js
|
||
|
assert.strictEqual(euler119(), 248155780267521);
