X squared times x squared equals?

Answer 1

x^2 * x^2 = x^4. When multiplying two variables with exponents, you simply have to add the exponents together, keeping the same variable. So in this case you'd add 2+2 to get a variable to the 4th power.

Answer 2

The answer depends on the value of x, so unless you provide x, this can not be answered.
