Please i need help When is the product of the square root of a prime number and a nonzero rational number a rational number?
lidiya [134]

Answer:

The product of the square root of a prime number and a nonzero rational number is a irrational number.

Step-by-step explanation:

Given that,

When is the product of the square root of a prime number and a nonzero rational number a irrational number.

We know that,

Prime number :

Prime number is that number whose has a two factor. first factor is one and second is themselves.

The square root of a prime number is irrational number.

Rational number :

Rational number is that number which is in fraction form.

For example : \dfrac{p}{q}

Here, p and q are integers

We need to proof the product of  the square root of a prime number and a nonzero rational number is a rational number

Using given data

Suppose, the square root = √5

Rational number  = \dfrac{2}{3}

We need to calculate the product of the square root of a prime number and a rational number

Using formula of product

R=P\timesQ

Where, P = square root of a prime number

Q= rational number

Put the value into the formula

R=\sqrt{5}\times\dfrac{2}{3}

R=\dfrac{2\sqrt{5}}{3}

Hence, The product of the square root of a prime number and a nonzero rational number is a irrational number.

He base of a pentagonal prism has an area of 2.4 m2. The prism has a volume of 4.8 m3. What is its height? Use sketches, formula
77julia77 [94]

Answer:

The height of the prism is 2m

Step-by-step explanation:

Given;

The volume of pentagonal prism, V = 4.8 m^3

Area of the prism, A = 2.4 m^2

To determine the height of the prism, we consider the following;

Volume of any prism = Area of the prism x height of the prism

Height of the prism = volume of the prism / Area of the prism

Height of the prism = 4.8 / 2.4

Height of the prism = 2 m

Therefore, the height of the prism is 2m
