is it y7?

2. anonymous

y^7 *

3. BloomLocke367

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

4. anonymous

yes

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 ?
