I'd like to help you, but I'm not sure what this problem is supposed to be. You can use the symbol ^ when using exponents. For example, 2x to the 4th power can be typed 2x^4. Perhaps you can repost with a clearer example.

i'm going to write the problem a little differently for simplicity. the carrots show "to the power of..." the parenthesis means multiply

((2x)^4)(3x^3)^2

first you are going to mulitply the exponents for the term (3x^3)^2:

3x^6

so now you have ((2x)^4)(3x^6)

now you combine everything. add the exponents together:

(3)2x^10

and multiply the 3 and 2:

6x^10

Get it?

If your problem is as Marie has stated, then you can proceed as follows:

(2x)^4 * (3x^3)^2 -->I'll use * to mean multiply.

(2x)^4 = 16x^4 -->take 2^4 and x^4, since there are parentheses around 2x.

(3x^3)^2 = 9x^6 -->square the 3 and x^3.

Multiplying the two together:

16x^4 * 9x^6 = 144x^10

I hope this is what you were asking.

oh! sorry! i forgot to distribute the exponent to the numbers, i just distributed to the variablees. MathGuru is correct. Agian, sorry. Thanks MathGuru for catching my mistake!!!

Glad to help!
