@*57=3570

I’m not sure what you mean by "@*57=3570". Do you mean:

• The symbols @ and * are placeholders for two operations you want to determine, applied to 57, that give 3570? If so, what operations are allowed (standard +, −, ×, ÷, exponent, concatenation, etc.)? Can we introduce constants?

Or

• Do you want to fill in two operators in a specific equation form (like (57 @) * 57 = 3570 or 57 @ (57 * 57) = 3570)? If yes, please specify the exact structure.

If you just want a quick way to pair two operations to reach 3570 from 57, here are two simple interpretations (allowing a constant):

• Example 1 (allowing a constant): Let @ mean “add 300” and * mean “multiply by 10”.

  • 57 @ → 57 + 300 = 357
  • then 357 * → 357 × 10 = 3570

• Example 2 (another two-step form): Let @ mean “multiply by 62” and * mean “add 36”.

  • 57 @ → 57 × 62 = 3534
  • 3534 * → 3534 + 36 = 3570

If you want only standard arithmetic using no extra constants, or you have a specific structure in mind (like (57 ? 57) ? ? = 3570 or similar), tell me the constraints and I’ll solve it accordingly.
