-2(-3)^3-5

Solution

- 2 (- 3)^{3} - 5

49

Solution steps

- 2 (- 3)^{3} - 5

Follow the PEMDAS order of operations

Calculate exponents

(- 3)^{3} : - 27

(- 3)^{3}

Apply exponent rule:

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

n

is odd

(- 3)^{3} = - 3^{3} = - 27

= - 27

= - 2 (- 27) - 5

Multiply and divide (left to right)

- 2 (- 27) : 54

- 2 (- 27)

Apply rule

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

- 2 (- 27) = 2 \cdot 27 = 54

= 54

= 54 - 5

Add and subtract (left to right)

54 - 5 : 49

54 - 5

54 - 5 = 49

= 49

= 49

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

1 - (\frac{1}{6} - \frac{1}{3})

5 + [2 - ((4 + 5 - 3) + 6)] - 1 - (3 + 5)

10 \cdot 1 0^{2}

- 3 (0) + 2
