144

Solution steps

(6)^{2} - 4 (1) (- 27)

Follow the PEMDAS order of operations

Calculate exponents

(6)^{2} : 36

(6)^{2}

(6)^{2} = 36

= 36

= 36 - 4 (1) (- 27)

Multiply and divide (left to right)

4 (1) (- 27) : - 108

4 (1) (- 27)

4 (1) = 4

4 (1)

Apply rule:

(a) = a

(1) = 1

= 4 \cdot 1

Multiply the numbers:

4 \cdot 1 = 4

= 4

= 4 (- 27)

Apply rule

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

4 (- 27) = - 4 \cdot 27 = - 108

= - 108

= 36 - (- 108)

Add and subtract (left to right)

36 - (- 108) : 144

36 - (- 108)

Apply rule

- (- a) = + a

- (- 108) = + 108

= 36 + 108

36 + 108 = 144

= 144

= 144

\frac{( 4 - 5 ) ^{2} + ( 5 - 5 ) ^{2} + ( 6 - 5 ) ^{2}}{3}
