What is Square Root of 1

• Square root of 1 is written as $\sqrt{1}$ (Radical form).
• Square root of 1 = $\sqrt{1}$ = $\sqrt{1 \times 1}$ = 1
• In the exponential form, the square root of 1 is expressed as $(1)^\frac{1}{2}$.

We will now calculate the square root of 1 by Prime Factorisation.

Square Root of 1 By Prime Factorization Method

• Step 1: Prime factors of 1:
• Step 2: Prime factors of 1 in pairs:
• Step 3: Now square root of 1:

$\sqrt{1} = \sqrt{}$

$\sqrt{1} = \sqrt{ ^2}$

$\sqrt{1} = 1$

Therefore, the square root of 1 is ±1
