Answer 2

Answer:

$\sqrt{64}$ is number which is not a surd.

Step-by-step explanation:

Explanation:

• An expression with a square root, cube root, or other root symbol is called a surd.

• Since the decimals of irrational numbers do not finish or recur, they cannot be expressed properly in decimal form. Surds are used to write irrational numbers precisely.
• $\sqrt{64}$, this  number is reduced to a rational number rather than an irrational number.

• It is obvious that $\sqrt{64}$ does not contain any irrational terms like square root, cube root, or any higher degree root

Hence, $\sqrt{64}$ is not a surd.
