\bf 3\sqrt[3]{2a} -6\sqrt[3]{2a}\qquad \stackrel{add ing~like-terms}{\implies }\qquad -3\sqrt[3]{2a}

Answer:

-3\sqrt[3]{2a}

Step-by-step explanation:

We have been given a  radical expression 3\sqrt[3]{2a} -6\sqrt[3]{2a} and we are asked to write our given expression in simplest form.

Using exponent property \sqrt[n]{x}=x^{\frac{1}{n} we can write our given expression as:

3*(2a)^{\frac{1}{3}}-6*(2a)^{\frac{1}{3}}

Since we can add or subtract variables with same powers and we have like bases and like exponents for our given expression, so we can subtract 6*(2a)^{\frac{1}{3}} from 3*(2a)^{\frac{1}{3}}

-3(2a)^{\frac{1}{3}}

Using exponent property x^{\frac{1}{n}=\sqrt[n]{x} we will get,

-3\sqrt[3]{2a}

Therefore, our given radical expression simplifies to -3\sqrt[3]{2a}.

Ava estimates that 475 songs will fit on her iPad. The actual amount of songs that fit is 350. Find her percent of error.
alukav5142 [94]

Given:

Ava estimates that 475 songs will fit on her iPad.

The actual amount of songs that fit is 350.

To find:

The percent of error.

Solution:

We know that,

\text{Percent error}=\dfrac{\text{Estimated values - Actual value}}{\text{Actual value}}\times 100

Putting the given values, we get

\text{Percent error}=\dfrac{475-350}{350}\times 100

\text{Percent error}=\dfrac{125}{350}\times 100

\text{Percent error}=\dfrac{250}{7}

\text{Percent error}\approx 35.71\%

Therefore, the percent of error is 35.71%.
