Final answer:
The simplified form of (3x4)3 is found by cubing the digit and multiplying the exponent by 3, resulting in 27x12.
Step-by-step explanation:
The simplified form of the expression (3x4)3 involves applying the cubing of exponentials rule. This rule states that when cubing an exponential expression, you cube the base number and multiply the exponent by 3.
Hence, we cube the digit 3, which becomes 33 or 27, and multiply the exponent 4 by 3, which gives us 12. The final simplified expression is therefore 33x12, or 27x12.
