Solution steps

(- 4)^{2} + 6 (- 4) + 8

Follow the PEMDAS order of operations

Calculate exponents

(- 4)^{2} : 16

(- 4)^{2}

Apply exponent rule:

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

n

is even

(- 4)^{2} = 4^{2} = 16

= 16

= 16 + 6 (- 4) + 8

Multiply and divide (left to right)

6 (- 4) : - 24

6 (- 4)

Apply rule

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

6 (- 4) = - 6 \cdot 4 = - 24

= - 24

= 16 - 24 + 8

Add and subtract (left to right)

16 - 24 + 8 : 0

16 - 24 + 8

16 - 24 = - 8

= - 8 + 8

- 8 + 8 = 0

= 0

= 0

5^{2} - 6 (5) + 1

32 + 2 (5 \times (24 - 67 - 48 \div 24))

- 10 \times (- 5 - 12)

2^{2} \times (- 2) + (- 2) \times 2 + (- 2^{2})
