ty！for c how can I do ？it is like （5a-9b）+（-3a+5b）
Try expanding it out first on the left, then group the ones without the root together and the one with the root together, then you can compare it!
ok tqvm！
No problem!
erm.....how about （d）？ಥ_ಥ
Multiply the denominator over then divide the values on the right (basically cross multiply). Then rationalise it and simiplify.
I cant solve it..ಥ_ಥ it looks so weird..
Sorry, my app got some prob! My notification page doesnt work, i did the start of d in another answer! Hope it helps!
