Mr. Yueng graded his students’ math quizzes. Students came up with four different answers when solving the equation x3 = 22. Which answer is correct? x=223 x=22−−√3 x=±22−−√3 x=22−−√

x = 22--√3

Step-by-step explanation:

For this case we must solve the following equation:

x³ = 22

If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:

3√x^3 = 3√22

x=3√22

That is the exact solution of the equation. Its decimal solution is given by:

x = 3√22 = 2.8020

Hope this is the answer you are looking for☺.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
