roots

[abstract cradle]

How would i resolve this division between roots?

Would you be able to show your workings?

The question is to do with power laws- these are the ones relevant to the question. I don't want to give the answer straight away but say if you get stuck

thank you! i'll try again

With your working, you just want to solve the problem algebraically- don't substitute any numbers into a- You want your answer in terms of a

i got here, but im pretty sure i made a mistake somewhere

For one, I made a mistake as when I was working through I realise you need pretty much every power rule, which I didn't show above.

• The 1st 3 lines are well done- You have simplified the roots correctly
• With the last line, just be careful with adding fractions

Let me know if anything doesn't make sense, and I can try to rephrase

So your *a* term in the bottom left should be to the power of 3/2

Here is a worked solution, if you want to check your work at the end

I hope it offers some help

thank you so much, i really appreciate it! i got stuck again at a^3/2 and a^8/3 but i finally get it
