Solution

2 (- 2)^{3} + 6

- 10

Solution steps

2 (- 2)^{3} + 6

Follow the PEMDAS order of operations

Calculate exponents

(- 2)^{3} : - 8

(- 2)^{3}

Apply exponent rule:

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

n

is odd

(- 2)^{3} = - 2^{3} = - 8

= - 8

= 2 (- 8) + 6

Multiply and divide (left to right)

2 (- 8) : - 16

2 (- 8)

Apply rule

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

2 (- 8) = - 2 \cdot 8 = - 16

= - 16

= - 16 + 6

Add and subtract (left to right)

- 16 + 6 : - 10

- 16 + 6

- 16 + 6 = - 10

= - 10

= - 10

(- 1 - 2)^{2}

3 (3^{2} + 3) - 14 + 4 (5 - 2)^{2} - 21 \times 5

- 2^{3} + 2

1 - 4 \times (- 8)

8^{2} + 3 (36 \div 6) - 2
