## HelloKitty17 one year ago Choose the correct simplification of the expression (c2)9. a.c18 b.c11 c.c512 d. c

1. pooja195

$\huge~(c^2)^9$

2. pooja195

Is that what you mean?

3. OregonDuck

similar example (c3)4=c3∗4 (c3)4=c12 note: this isn't the answer to your question as it's just a similar example

4. HelloKitty17

I got b

5. OregonDuck

yup that is right

6. pooja195

-.-

When you raise a power to a power, you MULTIPLY powers.

I mean I got B LOL sorry had trouble there

9. e.mccormick

OregonDuck, b is not right...

10. Nnesha

$\huge\rm (x^m)^n = x^{m \times n}$

@e.mccormick i did the equation and i got stuck with A and B

12. pooja195

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

13. mathstudent55

@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.

14. e.mccormick

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

15. mathstudent55

16. e.mccormick

a) c18 b) c11 c) c512 d) c

17. OregonDuck

so a?

18. mathstudent55

Yes, @OregonDuck , A is correct.
