4^4x4^6

4^4x4^6 = 4^(4+6) = 4^10

Therefore, 4^4x4^6 is equal to 4^10.

To simplify this expression, we can combine the two exponents since the bases, which are both 4, are the same.

When you multiply two exponential expressions with the same base, you can add the exponents. Therefore, the simplified form of the expression is:

4^4 * 4^6 = 4^(4+6) = 4^10.

So, 4^4 * 4^6 is equal to 4 raised to the power of 10.
