8*x^3-3-(2)=0 \\ \\ (2^3x^3 - 3) - 2 = 0 \\ \\ Factoring: 8x^3-5 \\ \\ 8x^3 - 5 = 0 \\ \\ \boxed{\bf{x = \sqrt[3] 0.625 }}

1. You con solve the equation 8x^2-3=2 by following the proccedure below:

8x^2-3=2

8x^2=2+3
8x^2=5
x^2=5/8
x=
±√(5/8)
x=±√(5/(2²)(2))=

2. When you simplify, you obtain the following result:

x=±√(10/4)

3. Therefore, the answer is the first option:
x=±√(10/4)
