\[\sqrt{180}+5\sqrt{45}+8\sqrt{80}\] How would I solve this?
as in how u wan me to express this?
ok do it my way, can u divide 180 by 9 then by 4?
Assume all variables represent positive real numbers
rewrite the expression now after u divided 180 by 36 and 45 by 9 and 80 by 16

5,6,5
u get something like this... \[\sqrt{36\times5}+5\sqrt{9\times5}+8\sqrt{16\times5}\]
do u see the squares? 36, 9,16?
Yes
can u now solve the equation by taking out the squares and putting them outside of the root square?
