Answer:

\large\boxed{\sqrt[3]{\left(\dfrac{15}{4}\right)^2}}

Step-by-step explanation:

a^\frac{n}{m}=\sqrt[m]{a^n}\\---------------------\\\\\left(5\times\dfrac{3}{4}\right)^\frac{2}{3}=\left(\dfrac{5\times3}{4}\right)^\frac{2}{3}=\left(\dfrac{15}{4}\right)^\frac{2}{3}=\sqrt[3]{\left(\dfrac{15}{4}\right)^2}

Answer:

\large\boxed{C.\ \sqrt5}

Step-by-step explanation:

\left(5^\frac{3}{4}\right)^\frac{2}{3}\\\\\text{Use}\ (a^n)^m=a^{nm}\\\\5^{\frac{3}{4}\cdot\frac{2}{3}}=5^{\frac{1}{2}\cdot\frac{1}{1}}=5^\frac{1}{2}=\sqrt[2]5=\sqrt5

In the first semester, Jonas took seven tests in his math class. His scores were: 88 81 94 84 100 94 96.

The median is the middle-most number. First we need to put the numbers in order from lowest to highest:

81 84 88 94 94 96

The easiest way to find the median is to cross out the first and last number and then continue until you reach the middle.

So cross out 81 and 96:
84 88 94 94 are left.

Cross out 84 and 94:
88 and 94 are left.

Since we are left with 2 different numbers, we need to find the average of them and that’s our median. (88 + 94)/2 = 91

91 is the median.

The standard height of kitchen cabinets is 34.5 inches. What is the metric equivalent in centimeters?

An inch = 2.54 Centimeters. So take 34.5 × 2.54 and you will get 87.63 centimeters.
