1.

( - a {}^{3} )  {}^{8} \div ( {a}^{4} ) {}^{3}  = a {}^{24}  \div a {}^{12}  = a {}^{12}

2.

1. (a + 3)(a - 2) + (a - 3)(a + 2) =  {a}^{2}  - 2a + 3a - 6 +  {a}^{2}  + 2a - 3a - 6 = 2 {a}^{2}  - 12

2. (x - 2) {}^{2}  + (x - 1)(x + 1) = x {}^{2}  - 4x + 4 +  {x}^{2}  - 1 = 2 {x}^{2}  - 4x + 3

3.

1. 4x - xy = x(4 - y)

2.  - 4x {}^{6}  + 16x {}^{15}  =  - 4x {}^{6} (1 - 4x {}^{9} )

3. 4n - nc - 4 + c = (4 - c)(n - 1)

4. 6m {}^{2} n - 3m {}^{2}  + 2mn {}^{2}  - mn = m(2n - 1)(3m + n)

5. a {}^{2} b {}^{2}  -  \frac{16}{9}  = (ab -  \frac{4}{3} )(ab  +  \frac{4}{3} )

Надеюсь помогла :)
