Answer:

5^{\frac{1}{2} } =\sqrt{5}

Step-by-step explanation:

Here we need to use the following property

x^{\frac{a}{b} }=\sqrt[b]{x^{a} }

So, we use this property to rewrite the given expression

(5^{\frac{3}{4} } )^{\frac{2}{3} }

First, we multiply exponents to have only one

(5^{\frac{3}{4} } )^{\frac{2}{3} }=(5)^{\frac{3 \times 2}{4 \times 3}  }=(5)^{\frac{6}{12} }=5^{\frac{1}{2} }

Then, we apply the property to rewrite the expression

5^{\frac{1}{2} } =\sqrt{5}

Therefore, the right answer is the third choice.

The mean of Tom’s scores on 5 tests was 77.4%. The scores on his first four tests were 88, 77, 70, and 72. What was Tom’s score
kogti [31]

Answer:

88%

Step-by-step explanation:

First we multiply the mean by 5.

77.4 x 5 = 387

Then we add all of the test scores.

88 + 77 + 70 + 72 = 299

We subtract the total of the scores from 387, which we got from mulitplying the mean by 5.

387 - 299 = 88

Therefore, Tom's score on his fifth test was an 88%.

Hope this helps!
