No hard feelings but there’s first graders in China who can do this in 2 seconds.

The answer must come with working out.

X²=32

X=√32

Y√32=16

√32(y)²=16 ( I mean the whole root)

By squaring both sides we get

32(y)²=256

By dividing both sides by 32 we get

Y²=8

Also please forgive me for incorrect solution , i haven't been taught algebra yet. But I did have other ways of learning it .btw this was all done mentally , no use of calculators .

x^2=32

x=sqrt 32

xy=16

√32y=16

y=16/√32

y^2=(16/√32)^2

y^2=256/32

y^2=8
