    do you mean \[5x(2)\] or \[5x^2\]?

    its okay. first thing is first, what do you do with the exponets?

    what equation would you have now?

    x^10 my bad

    the equation is actually (5^2)^2

    no you wouldn't. if you have \[5x^2\] and you spit it, you wouldn't have \[x^10\] you would get \[5x^1\] and \[5x^1\] now what would you do with them?

    okay, when you split up \[5x^2\] you would get \[5x\] and \[5x\] what would you do with the two \[5x\]

    no. you wouldn't divide. you remember PEMDAS? you have this equation, \[5x(5x)\] what would you do now?

    okay, first when you see something like oh, lets say: 5(2) it means to multiply. so if you have \[5x(5x)\] you would multiply them. and thus you would get:

    x^10 was correct. why did u say otherwise ?

    no its not, the answer would be \[25x\] you wouldn't do it as the exponet

    look: \[5x^2\] \[5x(5x)\] \[25x\] 5 times 5 isn't 10, its 25.
