180=2×2×3×3×5
root 180= root(2×2×3×3×5)
root 180=2×3× root5
root 180= 6 root5
therefore 5 is the number which should be multiplied to 180 so that it will become a perfect square.
180×5=900.
therefore, root of 900 =30
root 180= root(2×2×3×3×5)
root 180=2×3× root5
root 180= 6 root5
therefore 5 is the number which should be multiplied to 180 so that it will become a perfect square.
180×5=900.
therefore, root of 900 =30
