What is x^2 times x^2?

x^2 * x^2 = (x*x)*(x*x) = x*x*x*x = x^4

or,

x^2 * x^2 = x^(2+2) = x^4

or,

x^2 * x^2 = (x^2)^2 = x^(2*2) = x^4

To find the product of two numbers with the same base, you add their exponents. In this case, x^2 multiplied by x^2 can be rewritten as x^(2+2), which simplifies to x^4. Therefore, x^2 multiplied by x^2 is equal to x^4.
