Need help on math problems!?

Is √(-12) irrational, rational, or imaginary?

Is √(49)/√(100) irrational, rational, or imaginary?

    1. Imaginary

    2. Rational -> 7*10=70

    Square roots of a negative number are always imaginary so sqrt(-12) is imaginary.

    (sqrt[49]) / (sqrt[100]) = 7/10 which is rational.

    sqrt(-12) is imaginary as it is the square root of a negative number.

    sqrt(49)/sqrt(100) = 7/10 is rational as it is a normal fraction
