Answer:

Let's just assume there is no plus sign there as it seems like a mistake...

Answer #= 12x^4#

Explanation:

Here we just really need to use the standard index rule

where #a^m * a^n = a^(m+n)#

Assuming there is no #+# as it looks like a mistake we get:

#4x^2 * 3x^2#

To do this, we must first multiply the coefficients

#therefore 4 * 3 =12#

Next up is the powers. Using the previous index law mentioned:

#x^2*x^2 = x^4#

Treating the terms together we #therefore# get

#3x^2 * 4x^2 = 12x^4#
