30

Solution steps

(- 14)^{2} - 17 (14) + 72

Follow the PEMDAS order of operations

Calculate exponents

(- 14)^{2} : 196

(- 14)^{2}

Apply exponent rule:

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

n

is even

(- 14)^{2} = 1 4^{2} = 196

= 196

= 196 - 17 (14) + 72

Multiply and divide (left to right)

17 (14) : 238

17 (14)

Apply rule:

(a) = a

(14) = 14

= 17 \cdot 14

Multiply the numbers:

17 \cdot 14 = 238

= 238

= 196 - 238 + 72

Add and subtract (left to right)

196 - 238 + 72 : 30

196 - 238 + 72

196 - 238 = - 42

= - 42 + 72

- 42 + 72 = 30

= 30

= 30
