b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.
square root of 125/80 = 1.25 or 5/4
5
The square root of 125 in radical form is 5 x (square root of 5).
The cube root of 125 is 5; the square of 5 is 25.
1) 125 is the square root of 15625. 2) √125 = √(25 x 5) = √(52x 5) = 5√5
25
sqrt(125) = 11.18034 cube root is 5.
sq. root of (80/125)= sq. root of [(9)(2)(5)/(25)(5)]= (sq. root of 9)(sq. root of 2)/sq. root of 25= (3/5)sq. root of 2
You look for the largest perfect square, and take it out. In this case: root(125) = root(25 x 5) = root(25) x root(5) = 5 x root(5).
square root of 125= 25 times 5 under the radical (25 has a square root so you can take that out of the radical)= 5 times the square root of 5 (Thats your final answer with no calculator)
You first find a factor of 125 that is also a perfect square. It is 25. Then, write 125 as 5(25). Then, square root the 25, and therefore your answer is 5*sqrt5.
