Root Properties & Formulas

Property Formula Example
Product Rule √(a×b) = √a × √b √(4×9) = √4 × √9 = 2 × 3 = 6
Quotient Rule √(a/b) = √a / √b √(16/4) = √16 / √4 = 4 / 2 = 2
Power Rule (√a)² = a (√5)² = 5
Nth Root ⁿ√(aᵐ) = a^(m/n) ³√(8²) = 8^(2/3) = 4

Perfect Squares

√1 = 1
√36 = 6
√4 = 2

Square Root Calculator Answers

What does the square root calculator do?

It calculates the square root of any positive number. This helps you find the value that, when multiplied by itself, gives the original number.

Can it handle decimals and large numbers?

Yes, the calculator supports both decimal numbers and very large values, delivering accurate results with up to several decimal places.

What about negative numbers?

Square roots of negative numbers are not real numbers. If you input a negative value, the calculator will either show an error or give the result in terms of imaginary numbers (like √-4 = 2i).

Is this useful for students and professionals?

Definitely. It’s useful in math, engineering, physics, and finance when solving equations, analyzing data, or simplifying expressions.
