The square roots of some numbers are rational: eg sqrt(4) = 2, sqrt(0.04) = 0.2, sqrt(400) = 20 The square roots of some numbers are irrational eg sqrt(2) = 1.414 (approx), sqrt(0.02) = 0.1414 (approx), sqrt(200) = 14.14 (approx) The square roots of negative numbers are neither rational nor irrational, but imaginary.
20 squared is 400 which is a rational number
No because 400 is a rational number that can be expressed as a fraction in the form of 400/1
Square root of 400 simplified is 20.
