Question

64x^3 – 343 = solve

Answer 1

Hello Mate!

Solution for 64x^3-343=0 equation:

Simplifying:

$64x^3 + -343 = 0$

Reorder the terms:

$-343 + 64x^3 = 0$

Solving:

$-343 + 64x^3 = 0$

Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. 
Add '343' to each side of the equation.

$-343 + 343 + 64x^3 = 0 + 343$

Combine like terms: $-343 + 343 = 0$
$0 + 64x^3 = 0 + 343$
$64x^3 = 0 + 343$

Combine like terms: $0 + 343 = 343$
$64x^3 = 343$

Divide each side by '64'. $x^3 = 5.359375$

Simplifying:
$x^3 = 5.359375$

Reorder the terms:
$-5.359375 + x^3 = 5.359375 + -5.359375$

Combine like terms: $5.359375 + -5.359375 = 0.000000$
$-5.359375 + x^3 = 0.000000$

The solution to this equation could not be determined though:

$x=1.75$
