D is a surd bcchhhhhvvvgfzfchc hc

Answer 2

Answer:

d) $\sqrt[3]{625}$

Step-by-step explanation:

Surd means irrational. You just need to simplify all and check which will be an irrational number.

a) 216 = 6 x 6 x 6 So,

   $\sqrt[3]{216} = 6$ which is rational

b) 16 = 2 x 2 x 2 x 2 So,

   $\sqrt[4]{16}$ = 2 which is rational

c) 169 = 13 x 13

   $\sqrt []{169} = 13$ which is rational

d) 625 = 5 x 5 x 5 x 5

   Here we can't make pair of 3 numbers. So this will be irrational number.

Hope you understood :)
