1.12^4 × 9^5 × 4
= ( 3 × 4 ) ^4 × ( 3^2 )^5 × 4
= 3^4 × 4^4 × 3^10 × 4
= 3^4 + 10 × 4^4 + 1
= 3^14 × 4^5
2. 8^2 × 6^4 × 27
= ( 2^3 )^2 × ( 2 × 3 )^4 × 3^3
= 2^6 × 2^4 × 3^4 × 3^3
= 2^6 + 4 × 3^ 4 + 3
= 2^10 × 3^7
= ( 3 × 4 ) ^4 × ( 3^2 )^5 × 4
= 3^4 × 4^4 × 3^10 × 4
= 3^4 + 10 × 4^4 + 1
= 3^14 × 4^5
