Answer:

Students level of knowledge is higher in accountancy (Y) compared to statistics (X).

Step-by-step explanation:

The level of knowledge of the students in each subject can be known by comparing the mean score of the subjects.

Marks of the students in statistics (X) are: 63 64 62 32 30 60 47 46 35 28

mean = $\frac{63 +64+62+32+30+60+47+46+35+28}{10}$

= $\frac{467}{10}$

= 46.7

The mean mark of students in statistics (X) is 46.7.

Marks of students in accountancy (Y) are: 68 66 35 42 26 85 44 80 33 72

mean = $\frac{68+66+35+42+26+85+44+80+33+72}{10}$

= $\frac{551}{10}$

= 55.1

The mean mark of students in accountancy (Y) is 55.1.

It can be inferred that students level of knowledge is higher in accountancy (Y) compared to statistics (X).

How are exponents and radicals used to present roots of real numbers

MissTica

Answer:

$\sqrt[n]{a} =a^{\frac{1}{n}}$

Explanation:

Roots of real numbers can be represented by radicals or by exponents.

First, I present some examples to show how exponents and radicals are related, and then generalize.

$\sqrt{4}=4^{(\frac{1}{2})}=(2^2)^\frac{1}{2}=(2)^{\frac{2}{2}}=2^1=2\\\\\\\sqrt{25}=(25)^{\frac{1}{2}}=(5^2)^{\frac{1}{2}}=(5)^{\frac{2}{2}}=5^1=5$

$\sqrt[3]{8}=(8)^{\frac{1}{3}}=(2^3)^{\frac{1}{3}}=(2)^{\frac{3}{3}}=2^1=2$

When you write 5² = 25, then 5 is the square root of 25.

And in general, if n is a positive integer and $a^n=x$ , then $a$ is the nth root of x.

Also, if n even (and positive) and $a$ is positive, then $a^{\frac{1}{n}}$ is the positive nth root of $a$

Thus,

$\sqrt[n]{a} =a^{\frac{1}{n}}$
