Solution

- 4

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 : - 4

4 - 8

4 - 8 = - 4

= - 4

= - 4
