Calculate exponents

(- 4)^{3} : - 64

(- 4)^{3}

Apply exponent rule:

(- a)^{n} = - a^{n},

n

is odd

(- 4)^{3} = - 4^{3} = - 64

= - 64

2 (- 64) : - 128

2 (- 64)

Apply rule

a \cdot (- b) = - a \cdot b

2 (- 64) = - 2 \cdot 64 = - 128

= - 128

= - 128 + 6

- 128 + 6 : - 122

- 128 + 6

- 128 + 6 = - 122

= - 122
