x³=8

x³=27

x³=64

Step-by-step explanation:

A rational number is one formed by dividing integers. This means a rational number can be expressed as a ratio of two integers. Examples of rational numbers are;

Given in the question;

x³=8 x=∛8 = 2 can be formed from 2/1 ⇒ equation has rational number

x³=16 x=∛16 = 2.5198421 irrational

x³=27x=∛27 = 3rational

x³=64x=∛64 =4rational

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
