A student says that it 5x^2 =20,then x must be
equal to 2. Do you agree or disagree with the
student? Justity your answer.


Sagot :

  • I agree with the student.
  • Justification:
  • [tex] {5x}^{2} = 20 \\ = > {x}^{2} = \frac{20}{5} \\ = > {x}^{2} = 4 \\ = > x = \sqrt{4} \\ = > x = 2[/tex]
  • Therefore, x must be equal to 2.
  • So his statement is right.

Hope you could get an idea from it.
