    Explanation

    Formula- If you can express the expression in the form (ax+1)na\frac{{{{\left( {ax + 1} \right)}^n}}}{a} the remainder will become 1 directly. In such a case no matter how large the power n is, the remainder is 1. ∴ Remainder in 82 157 /9, is equal to (9 × 9 + 1) 157 /9, which is equal to the remainder in 1 157 /9 Hence, required remainder = 1.
