Surds are based on roots. Root 8 can be split into root 4 and root 2; as there's a root to 4, get that number, and multiply it by the remaining root. So root 8 = 2 root 2. Root 40 would be 2 root 10 Root 48 would be root 4, root 4, root 3 Root 48 = 4 root 3.
4 square root 3 + 4 cube root 3 is 12.6972015
9 square root 4 minus 12 square root 4 = -6
the square root of 4 is 2 square root 2
4 square root of -9 = 4 square root of (-1)(9) = 4 square root of (i29) = 4(3i) = 12i

square root is 8 (8 x 8 = 64)cube root is 4 (4 x 4 x 4 = 64)
9 square root 4 minus 12 square root 4 = -6
16 root 24
the square root of 4 is 2 square root 2
4 square root of -9 = 4 square root of (-1)(9) = 4 square root of (i29) = 4(3i) = 12i
The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).

The square root of 4 is 2
cube root (4) = 1.58740105.
You can take out the perfect square 4: root(40) = root(4 x 10) = root(4) x root(10) = 2 root(10).
