1. lisa2345

is it y7?

2. lisa2345

y^7 *

3. BloomLocke367

is that supposed to be $$(y^3)^4$$?

4. lisa2345

yes

5. BloomLocke367

When you multiply 2 powers, you add them. So say you have $$x^3\times x^2$$, you'd get $$x^5$$. BUT when you take a power to a power, you have to multiply them. So $$(x^3)^2$$ would be $$x^6$$. Does that make sense? In your case, you're taking a power to a power. So, rethink your answer and let me know what you get.

y^12 ?

I'm sorry, I have to go, but just use what I said earlier.
