What is equal (1 + 5k + 3j ) (1 + 2i+ 3k)-1?
Write the coefficient at j & k ?
 
please answer the questions in the attachments are as both are interrelated

What are i, j & k? Are you performing dot-product of vectors?

I don't think you meant "components"; that would make them real numbers. Probably you meant "unit vectors".

But then what does 1 + 5k + 3j mean, where you seem to be adding a scalar and two vectors?

Please show us the original problem exactly as given to you; an image will be good (even if it's in a different language).

(And what attachments are you referring to?)
