Question

8x3-3=2 Solve for x.

Answer 1

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

Your answer: Option C

Answer 2

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)
