Am I wrong here?

Could any check whether I am wrong here or the website is wrong. I have substituted my answers to 2dp in and they are very close to the answers given in the first equation but when the answers from the website are substituted in they are not close at all. Am I doing something wrong here?
Thanks

I get the same as you.

I might be wrong but I'm also getting the same answer as you are.

P.S I substituted the answers from the website as well, and yeah it is not satisfying the equation. So, maybe the website is not right, it happens sometimes!

I got what you got by substitution.Maybe the answers are wrong.
