Radicals w/rational exponents
posted by Michelle .
Could someone please help me with this.
Assume nonnegative and simplify.
v45 + v80  3 v20
I couldn't figure out how to insert the radical sign so the v represents the radical sign.
(3v5 + v3)(v2 + 2v5)
(v3+ 4v7)2square
ans=root of 5
sqrt45 + sqrt80  3 sqrt20
sqrt9*5 + sqrt16*5  3 sqrt4*5
3sqrt5+ 4sqrt56sqrt5 then combine
(3v5 + v3)(v2 + 2v5)
3v10 + 6v25 + v6 + 2v15
you can combine some, the sqrt 5 appears in three terms.
