Answer: If you take the square root of a number that is not a perfect square, it is going to be irrational. And then if you just take that irrational number and you multiply it, and you divide it by any other numbers, you're still going to get an irrational number. So square root of 8 is irrational. You divide that by 2, it is still irrational.

Simplify the expression

SashulF [63]

Answer:

The simplified form of given expression $\frac{15xy}{5x^{\frac{1}{2}}y^2}$ is $\frac{3x^{\frac{1}{2}}}{y}$

Step-by-step explanation:

Given: Expression $\frac{15xy}{5x^{\frac{1}{2}}y^2}$

We have to write the given expression in simplified form,

Consider the given expression $\frac{15xy}{5x^{\frac{1}{2}}y^2}$

Divide the numbers $\frac{15}{5}=3$

we get,

$=\frac{3xy}{y^2x^{\frac{1}{2}}}$

Apply exponent rule , $\frac{x^a}{x^b}\:=\:x^{a-b}$

$\frac{x}{x^{\frac{1}{2}}}=x^{1-\frac{1}{2}}=x^{\frac{1}{2}}$

we get,

$=\frac{3yx^{\frac{1}{2}}}{y^2}$

Cancel y term, we have,

$=\frac{3x^{\frac{1}{2}}}{y}$

Thus, The simplified form of given expression $\frac{15xy}{5x^{\frac{1}{2}}y^2}$ is $\frac{3x^{\frac{1}{2}}}{y}$
