Solve the equation: <img src="https://tex.z-dn.net/?f=5%5Ex%5E%28%5Ex%5E-%5E1%5E%29%3D1" id="TexFormula1" title="5^x^(^x^-^1^)=1

Tomtit [17]

The concept:

We are given the equation:

$5^{x(x-1)} = 1$

Which can be simplified as:

$5^{x^{2} - x} = 1^{1}$

Since any number to the power '0' is 1

x² - x must be equal to 0 for the given equation to be true

Solving for x:

x² - x = 0

x(x-1) = 0

now, we can divide both sides by either x OR x-1

So we will see what we get for either choice:

x = 0/(x-1) x-1 = 0/x

x = 0 x = 1

Hence, the value of x is either 0 or 1

Use the minimum and maximum data entries and the number of classes to find the class width, the lower class limits, and the uppe

deff fn [24]

Answer:

The class width is $C_w \approx 13$

Step-by-step explanation:

From the question we are told that

The upper class limits is $max = 121$

The lower class limits is $min = 14$

The number of classes is $n = 8 \ classes$

The class width is mathematically represented as

$C_w = \frac{max - min}{n }$

substituting values

$C_w = \frac{121 - 14}{8 }$

$C_w = 13.38$

$C_w \approx 13$
