-3(-4)^3-2

Solution

- 3 (- 4)^{3} - 2

190

Solution steps

- 3 (- 4)^{3} - 2

Follow the PEMDAS order of operations

Calculate exponents

(- 4)^{3} : - 64

(- 4)^{3}

Apply exponent rule:

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

n

is odd

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

= - 64

= - 3 (- 64) - 2

Multiply and divide (left to right)

- 3 (- 64) : 192

- 3 (- 64)

Apply rule

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

- 3 (- 64) = 3 \cdot 64 = 192

= 192

= 192 - 2

Add and subtract (left to right)

192 - 2 : 190

192 - 2

192 - 2 = 190

= 190

= 190

(\frac{3}{4} \cdot \frac{1}{4}) \cdot 4

(- 2)^{2} + 4 (- 2) - 3

66 \div (5 + 1) \cdot 4 - 2^{3}

5 \times (+ 12) - 4 (7 + 4) + 8 (6 - 3)

6 0^{2} + 2 5^{2}
