no, it's 7 sqrt 27-sqrt147+6sqrt300

Your change doesn't really change the problem at all.
7√27 - √147 + 6√300 =
7√(9×3) - √(49×3) + 6√(100×3) =
7√9√3 - √49√3 + 6√100√3 =
7×3√3 - 7√3 + 6×10√3 =
21√3 - 7√3 + 60√3 =
74√3

first, you gotta simplify the 7rad27, rad147 and rad 300 into smaller numbers so that they are smaller and then possibly you can subtract them. you gotta get the same numbers in the rad sign. if that doesnt work, the answer would be the simplified form of what you simplified. the answer should be 21rad sign 3- 7 radsign 3 +10 radsign 3, which equals to 24 rad 3 =] hope that helps ya

7*sqrt(27) - sqrt(147) + sqrt(300)
=21*sqrt(3) - 7*sqrt(3) + 10*sqrt(3)
=(21- 7 +10)*sqrt(3)
=24* sqrt(3)
