(1 point) For each space W, determine a basis for W! Note that if you do not need a basis vector, then write 0 for all entries of that basis vector. For example, if you only need 2 vectors in your basis, then write 0 in all boxes corresponding to the third vector 1) Let W= la + 2b + 5c + Od 2a + 5b + 11c + 2d -5a +...

Please double check my answers? If they're wrong can you explain how to do it right? My math book doesn't have examples for all of these scenarios and I really don't want to fail this assignment. I don't normally look for help online, but I'm kinda desperate. When I couldn't find a symbol for the exponent I used the ^ 1. 18r⁴ s⁵ t⁶ ÷ -3r² s t³ = ?
