Homework problem

Granddaughter asked me for help on this, I’ve never heard of surd form before this.

Can anyone explain how to do this. Please show working out. 😀

Thanks for the answer(s). In my whole 73 years I've never heard the term 'surd form' before.

I'm still a loss at how to do it, looks like the granddaughter's on her own here :D

I must have nicked off school that day...

I don't remember it at all and I had to do a year's extra maths at the Poly as my degree course needed A level maths, which I didn't have.

I did a year of maths for computer science at uni too. To be honest it only covered o level stuff though.

I did calculus irrational numbers and by extension surd form and imaginary numbers at o level maths.
