wow is that hard to read

3. anonymous

$\huge \sqrt{6x^7y^3}\times \sqrt{30x^8y^{21}}$?

4. Nnesha

y^{-3}

5. Astrophysics

$\huge \sqrt{6x^7y^{-3}} \times \sqrt{30x^8y^{21}}$

6. Astrophysics

I think that's it

7. anonymous

Yeah what he said is what i think it is

8. Astrophysics

$\sqrt{6x^7y^{-3}} \times \sqrt{30x^8y^{21}} \implies (6x^7y^{-3})^{1/2} \times (30x^8y^21)^{1/2}$ I think this may be easier for you to see

@Astrophysics It is my bad drawing on the computer isn't the easiest thing lol

10. Astrophysics

$\sqrt{x} \implies x^{1/2}$

11. Astrophysics

Orrrrrrrr $\large \sqrt{6x^7y^{-3}} \times \sqrt{30x^8y^{21}} \implies \sqrt{6x^7y^{-3} \times 30x^8y^{21}}$

12. Astrophysics

Now you can simplify easily

13. Astrophysics

lets ignore the 6*30 for now, lets play around with the variables, do you know how to simplify them?

14. anonymous

yes
