Question

Can someone pls help me solve this question the teacher is eating my head

Answer 1

= -2(-3)³- (-2)²+5

= -2*(-27) - 4 +5

= 54+5 -4 (don't forget to use bodmas)

= 55 Ans

note:

any negative number raised to an even power gives a positive number in result.

eg:

(-3)²= 9

(-3)³= - 27

hope it helps

good day:)
