Are square root numbers rational?
In general, not usually.The square root of an irrational number is always irrational.The square root of a rational number is usually irrational, but not always. You can tell by this test:If both the numerator and denominator of the number expressed as a simplified fraction are perfect square numbers (a number whose square root is a whole number), then the square root of the whole fraction will be rational.Example: Sqrt(4) =2 (the positive one). Sqrt(1) = 1. Both are perfect squares.So sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2. Another one: sqrt(4/9) = 2/3.
Square root of 9x7?
Two ways to look at it: 1). sqrt( 9 x 7 ) = sqrt( 63 ) = 7.93725 (rounded) 2). sqrt( 9 x 7 ) = sqrt( 9 ) x sqrt( 7 ) = 3 x sqrt( 7 ) = 3 x 2.64575 (rounded) = 7.93725
