To there fisrt one if its asking for the value of X it is x = 6
Or 2X3 two X to the 3rd power pretty sure
2 to the 9 power would be 512
These answers i believe are correct


Simplifying
2x * 2x * 2x + 5 = 0

Reorder the terms for easier multiplication:
2 * 2 * 2x * x * x + 5 = 0

Multiply 2 * 2
4 * 2x * x * x + 5 = 0

Multiply 4 * 2
8x * x * x + 5 = 0

Multiply x * x
8x2 * x + 5 = 0

Multiply x2 * x
8x3 + 5 = 0

Reorder the terms:
5 + 8x3 = 0

Solving
5 + 8x3 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.
5 + -5 + 8x3 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + 8x3 = 0 + -5
8x3 = 0 + -5

Combine like terms: 0 + -5 = -5
8x3 = -5

Divide each side by '8'.
x3 = -0.625

Simplifying
x3 = -0.625

Reorder the terms:
0.625 + x3 = -0.625 + 0.625

Combine like terms: -0.625 + 0.625 = 0.000
0.625 + x3 = 0.000

The solution to this equation could not be determined.
