Which describes a number that cannot be irrational? a number that can be written as the ratio of two integers

a number that represents the length of the diagonal of a square

a number that can be used to solve an algebraic equation

a number that represents the ratio of the circumference to the diameter of a circle

A rational number is a number that can be express as the ratio of two integers.

First option is correct.

           Where not be equal to zero.

Hence, A number that can be written as the ratio of two integers can not be irrational.

A number that cannot be irrational is:

A number that cannot be written as the ratio of two integers

Step-by-step explanation:

Irrational numbers can be defined as those numbers which cannot be written as in a form of Fraction (Ration of two integers).

E.g if we consider the value of constant pi

π = 3.14159265

and it goes on, that why we cannot write it in a form of simple fraction.

Another example of irrational number is under root of 2

√2 = 1.41421356

Hence, it also cannot be written as a simple fraction.

However, a number which can be written as a ratio of two integers is a rational number. e.g

2/5 , 1/4 etc

As a rational number can never be an irration number, so statement 1 is correct

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
