Yep it should be. After spending a while on hoping you would realise that root 4 is 2 I completely disregarded the sign lol.

Why would you multiply 3 root 7 by 3 root 3? Where are you getting this from?

Well you have 3 x 3 x root7 x root7 so do whatever you think is right here.

I'm not sure. I think root 7 stays and I multiply 3*3

so 9 root 7
19. I get stuck on these steps

3*3*root7*root7

3-3=9
root7*root7=7
(remember when you multiply roots you just multiply the numbers on the inside so here you get root 49 = 7 although its easier to just know that the same roots multiplied you just get rid of the root)

so its 9*7=63
