Answer:

x^12.

Step-by-step explanation:

x^4 times x^4 times x^4.

Since we don't know x and the 4's are exponents we just add them together.

The simplified expression of x^4 * x^4 * x^4 is x^12

The expression is given as:

x^4 * x^4 * x^4

Apply the law of indices

x^(4 + 4 + 4)

Evaluate the sum of the exponents

x^12

Hence, the simplified expression of x^4 * x^4 * x^4 is x^12
