Answer:

-------------

3x^2

Step-by-step explanation:

First lets simplify what is inside the square root

300x8

---------------

27x12

3 * 100 x^8

------------------

3 *9 x^12

The 3's cancel and we know a^b/ a^c = a^(b-c)

100/9 x^ (8-12)

100/9 x^-4

sqrt( 100/9 x^-4)

Put the negative exponent in the denominator and make it positive

sqrt( 100 / (9x^4) )

We know that sqrt( a / b) = sqrt(a) / sqrt( b)

sqrt(100)

----------------

sqrt( 9x^4)

-------------

3x^2

Which property would be used to show that the product of two rational is always rational

KatRina [158]

You multiply two rational numbers by multiplying numerators and denominators with each other. So, you have

$\dfrac{a}{b} \times \dfrac{c}{d} = \dfrac{ac}{bd}$

A rational number is a fraction where both numerator and denominator are integers. Since the product of two integers is an integer, the result fraction is also a rational number, because both $ac$ and $bd$ are integers.
