Answer:

(4n^2)/(21n +3) . . . . n ≠ -3/2 or 0 or 1/7

Step-by-step explanation:

$\dfrac{\left(\dfrac{14n^2+19n-3}{30n^2+45n}\right)}{\left(\dfrac{49n^2-1}{20n^3}\right)}=\dfrac{(2n+3)(7n-1)}{15n(2n+3)}\cdot\dfrac{20n^3}{(7n-1)(7n+1)}\\\\=\dfrac{20n^2}{15(7n+1)}=\boxed{\dfrac{4n^2}{21n+3}}$

Simplify: StartRoot StartFraction 27 x Superscript 12 Baseline Over 300 x Superscript 8 Baseline EndFraction EndRoot StartFracti

ale4655 [162]

The solution of the expression is $\rm \dfrac{9\times x^4}{100}$ .

Given that

Equation; $\dfrac{27x^{12}}{300x^8}$

We have to simplify the equation.

According to the question

To simplify the equation follow all the steps given below.

Equation; $\sqrt{\dfrac{27x^{12}}{300x^8}}$

Then,

$= {\dfrac{27x^{12}}{300x^8}}\\\\ = \dfrac{3\times 3\times 3 \times x^{8} \times x^{4}}{3 \times 100\times x^8}}\\\\=\dfrac{9\times x^4}{100}$

Hence, the required expression is $\rm \dfrac{9\times x^4}{100}$ .
