Smplify the radical expression. How many different ways can you write your answer?
mel-nik [20]

Answer:

2xy\sqrt[3]{2x^2z} and 2xy(2x^2z)^{\frac{1}{3}}.

Step-by-step explanation:

The given radical expression is

\sqrt[3]{16x^5y^3z}

We have to simplify the above expression.

The above expression can be written as

\sqrt[3]{(2\times 8)(x^{3+2})y^3z}

\sqrt[3]{(2\times 2^3)(x^3\times x^2)y^3z}    [\because a^{m+n}=a^ma^n]

\sqrt[3]{(2^3x^3y^3)(2x^2z)}

\sqrt[3]{(2xy)^3}\sqrt[3]{2x^2z}    [\because (ab)^m=a^mb^m]

2xy\sqrt[3]{2x^2z}    [\because \sqrt[n]{x^n}=x]

It can be written as exponent form.

2xy(2x^2z)^{\frac{1}{3}}    [\because \sqrt[n]{a}=a^{\frac{1}{n}}]

Therefore, the required expressions are 2xy\sqrt[3]{2x^2z} and 2xy(2x^2z)^{\frac{1}{3}}.

14 thanks you so much

Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.

1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81

2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...

Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.

Does anyone know the answer

The slope would represent how high you’re going and at what rate.

You are hiking uphill, because it’s adding, not subtracting..
