58 = 1 × 23 + 4 × 5 + 6 + 7 + 8 + 9
58 = 98 − 7 − 6 − 5 − 43 + 21
58 = 0^5 + 1^7 − 2^8 − 3^9 + 4^0 + 5^6 + 6^3 + 7^2 + 8^4 + 9^1
58 = 3^2 + 7^2
58 = (111 + 1)/(1 + 1) + 1 + 1
= (2 + 2 + 2)2 + 22
= (3 + 3/3)3 − 3 − 3
= (44 − 4 − 4)/4 − 4
= 55 + 5 − (5 + 5)/5
= ((6 + 6)/6)6 − 6
= 7 × 7 + 7 + (7 + 7)/7
= 8 × 8 − 8 + (8 + 8)/8
= 9 + (9 × 99 − 9)/(9 + 9)
