square root of 80 simplified= 16*5= 4 squared *5
√180 = √(4 x 9 x 5) = 6√5
sqrt (80) = sqrt (16x5) = 4 x sqrt(5)
It is simplified as 4 times the square root of 3. Hope this helps! dancinggirl25
5
As a simplified surd, it is 5*sqrt(15)
15 square root sign 5
5 square root 7 because 3 square root of 28 goes from 3 square root of 28 to 3 square root of 7 and 4 which then 4 condenses down to 2 and you add that to 3 then you get 5 square root of 7
9 times the square root of 5
√25 + √75 = 5 + √(25*3) = 5 + √25√3 = 5 + 5√3.
