AQA level 2 Further maths GCSE

do people remember what the q was for the x/y one?

do people remember what the q was for the x/y one?

4root x = 2 and y^-2 =25

What did u get for x/y

I think I got 40

Ohhhhh I got 80 😂

I got 80

-80

Ohhhhh I got 80 😂

Could anyone who has successfully finished the last question please explain how they reached their answer? Thanks

I got -80.... It said y was below zero, and because y^2 was 1/25 (I think...), y was either plus or minus 1/5. It had to be minus because the question said, so I did 16/(-1/5) which is -80. I hope that is right, because everyone else got something different. Anyway, it is almost the end of GCSEs!!!

4root x = 2 and y^-2 =25

you're correct.

oohhh ok thank you, i think i got -80?

What did you get for the question that said work out x and it was something like (number- root x)1/3=-2

Also the one that asked for the value of cosx

I got that cosx was - root 25/36. It's probably wrong

i think that's right but you could've simplified it to - 5/6
