Answer:
The correct operator for the exponential expression 3^5 ? 4^6 is > (greater than), because we can compare the values of the two exponents:
3^5 = 243
4^6 = 4096
Since 4096 is greater than 243, we can write:
3^5 < 4^6
or
4^6 > 3^5
Therefore, the correct operator for the exponential expression 3^5 ? 4^6 is > (greater than).
