Question

Rationalize the denominator in each expression 2/(√(x-12)).

Answer 1

Answer:

Step-by-step explanation:

Data given in the question:

$2/\sqrt{x-12}$

Task is to rationalize the expression.

Solution:-

To rationalize the denominator we have to multiply the numerator and denominator by the root of the denominator.

$=>2/\sqrt{x-12}$

root of $\sqrt{x-12}$ is $\sqrt{x-12}$

Multiplying the Nr and Dr by the root.

$=>(2/\sqrt{x-12}) *(\sqrt{x-12}/\sqrt{x-12})$

$=>2\sqrt{x-12}/(\sqrt{x-12}*\sqrt{x-12})\\=>2\sqrt{x-12}/x-12$
