function primeExponentials(x)
// x: a number

const xmath = require('extra-number');


xmath.primeExponentials(1);
// → []

xmath.primeExponentials(9);
// → [[3, 2]]

xmath.primeExponentials(63);
// → [[3, 2], [7, 1]]

xmath.primeExponentials(605);
// → [[5, 1], [11, 2]]

xmath.primeExponentials(53);
// → [[53, 1]]
