Question

Which among these is not true? ( (-x)^3=x^3
(xy)^3=x^3 y^3
(x/y)^3=x^3/y^3
x^3=(x)^3​

Answer 1

Answer:

( (-x)^3=x^3 is not true.

Step-by-step explanation:

${ - x}^{3} \: \: = \: \: - x \: \times \: - x \: \times - x$

Answer 2

Answer:

$- {x}^{3} = {x}^{3}$

Step-by-step explanation:

$- {x}^{3} = - x \times - x \times - x \\ {x}^{3} = x \times x \times x$

here

-x × -x = x^2

x^2 × -x = - x^3

that is, -x × -x × -x = -x^3

x × x × x = x^3
