Answer 2

To evaluate the expression 4x/y when x = √3 and y = √12, we substitute these values into the expression:

4(√3)/√12

To simplify this expression, we need to rationalize the denominator by multiplying the numerator and denominator by the conjugate of the denominator (√12):

(4√3 * √12) / (√12 * √12)

Simplifying further:

(4√3 * √12) / (√12 * √12) = (4√36) / 12

√36 = 6, so we have:

(4 * 6) / 12 = 24 / 12 = 2

Therefore, when x = √3 and y = √12, the expression 4x/y evaluates to 2.
