can someone help me on question 4-6 for 4 all i have don so far is rationalise the 10/root 3
to get 10 root3/3
for question 5 i put 4/3 as square root and 1/3 as root 3 then i simplified root4/3 to 2/3 and added 3 root3/3 but I'm not sure where to go from here

4) First, try and evaluate root(300/4), you should recognise that root(a/b) = root(a)/root(b). See what happens after that.
5) You've made a small error, root(4/3) = 2/root(3), not 2/3. Try going from there.
6) Although you don't have to, I like to convert mixed fractions to improper fractions. Then, evaluate the square root (it should come out to be 2) and add on (1/3)^1/2, having rationalised the denominator so that you can put it all as one fraction.

Hopefully this helps!
