Answer:26
Step-by-step explanation:The square root of 676 is 26, i.e. √676 = 26. The radical representation of the square root of 676 is √676. Also, we know that the square of 26 is 676, i.e. 262 = 26 × 26 = 676. Thus, the square root of 676 can also be expressed as, √676 = √(26)2 = √(26 × 26) = 26. Also, we can say that 676 is a perfect square.
The square root of 676 can be both positive and negative of 26 since 26 × 26 = 676 and (-26) × (-26) = 676. Therefore, the square root of 676 is ±26. However, “the square root” is often used to refer to the principal or non-negative square root. Thus, we write the positive number as the result unless specified.
