(-2)^2-(-2)^3

Solution

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

Solution

12

Solution steps

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

Follow the PEMDAS order of operations

Calculate exponents

(- 2)^{2} : 4

(- 2)^{2}

Apply exponent rule:

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

if

n

is even

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

= 4

= 4 - (- 2)^{3}

Calculate exponents

(- 2)^{3} : - 8

(- 2)^{3}

Apply exponent rule:

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

if

n

is odd

(- 2)^{3} = - 2^{3} = - 8

= - 8

= 4 - (- 8)

Add and subtract (left to right)

4 - (- 8) : 12

4 - (- 8)

Apply rule

- (- a) = + a

- (- 8) = + 8

= 4 + 8

4 + 8 = 12

= 12

= 12
