pooja195 · Answer

What is 
$$\huge 9 \times 2=???$$

mathstudent55 · Answer

@OregonDuck 
You gave a good example that was correct.
$(c^3)^4 = c^{12}$
showing that the exponents are multiplied.

Then the poster said the answer is C. c^11, which means the exponents were added, you said that was correct. Answer C. is incorrect bec the exponents need to be multiplied not added.

e.mccormick · Answer

$\huge\rm x^mx^n = x^{m + n}$  is what some people seem to be thinking about, but this problem is not in that form.
