Answer:

\frac{1}{4}

Step-by-step explanation:

<u>Approach 1 (trickier)</u>

\frac{2}{3}*\frac{7}{12}*\frac{9}{14}\\ \\ \frac{2*7*9}{3*12*14}\\ \\ \frac{126}{504}\\ \\\frac{1}{4}

<u>Approach 2 (easier)</u>

\frac{2}{3}*\frac{7}{12}*\frac{9}{14}\\\\\frac{2}{14}*\frac{7}{12}*\frac{9}{3}\\ \\ \frac{1}{7}*\frac{7}{12}*3\\ \\ \frac{1}{12}*3\\ \\ \frac{3}{12}\\ \\\frac{1}{4}

Use properties of rational exponents to simplify the expression. Assume that all variables represent positive numbers. Superscri
blsea [12.9K]

Hi, your question was incomplete hence I have attached the complete version of the question below.

Answer:

<u>5x^3 y^2</u>

Step-by-step explanation:

Using the property of the product of the exponents on the base and removing the parentheses,

(125x^9y^6)^(1/3) = (125)^(1/3) * (x^9)^(1/3) * (y^6)^(1/3)

= (125)^(1/3) * (x)^9*(1/3) * (y)^6*(1/3)

= 5 * (x)^3 * (y)^2                                                    

= 5 x^3 y^2

hence the required result is 5 x^3 y^2

how much 45% acid solution should be mixed with a 30% acid solution to make 450 ml of a 40% acid solution?
FromTheMoon [43]
We do as follows:

let x = amount of 45% solution
    y = amount of 30% solution

overall balance =>    x + y = 450
acid balance     =>    .45x + .30y = .40(450)

Solving simultaneously, we will have:

x = 300 mL
y = 150 mL

This is assuming that partial molar properties does not affect the volume greatly. Hope this answers the question. Have a nice day.
