simplify ((x-3)^1)^3+((x-3^2)^1)^3

simplify

((x - 3)^{1})^{3} + ((x - 3^{2})^{1})^{3}

2 x^{3} - 36 x^{2} + 270 x - 756

Solution steps

((x - 3)^{1})^{3} + ((x - 3^{2})^{1})^{3}

((x - 3)^{1})^{3} = (x - 3)^{3}

((x - 3^{2})^{1})^{3} = (x - 9)^{3}

= (x - 3)^{3} + (x - 9)^{3}

Expand

(x - 3)^{3} : x^{3} - 9 x^{2} + 27 x - 27

= x^{3} - 9 x^{2} + 27 x - 27 + (x - 9)^{3}

Expand

(x - 9)^{3} : x^{3} - 27 x^{2} + 243 x - 729

= x^{3} - 9 x^{2} + 27 x - 27 + x^{3} - 27 x^{2} + 243 x - 729

Group like terms

= x^{3} + x^{3} - 9 x^{2} - 27 x^{2} + 27 x + 243 x - 27 - 729

Add similar elements:

x^{3} + x^{3} = 2 x^{3}

= 2 x^{3} - 9 x^{2} - 27 x^{2} + 27 x + 243 x - 27 - 729

Add similar elements:

- 9 x^{2} - 27 x^{2} = - 36 x^{2}

= 2 x^{3} - 36 x^{2} + 27 x + 243 x - 27 - 729

Add similar elements:

27 x + 243 x = 270 x

= 2 x^{3} - 36 x^{2} + 270 x - 27 - 729

Subtract the numbers:

- 27 - 729 = - 756

= 2 x^{3} - 36 x^{2} + 270 x - 756

4 a + 5 + 4 a

(5 x^{2})^{- 2} \cdot 5^{3} x^{5}

(\frac{3 a + 1}{( 4 b )})^{3}

\frac{3}{( x - 5 )} - \frac{4}{( x + 5 )}

\frac{( 8 x ^{3} + y ^{3} )}{( 2 x + y )}
