Find the values.

(–10)3

Answer :

Here the number is negative.


So during multiplication care has to be taken of the sign.


The basic rules are:


Negative Number × Negative Number = Positive


Negative Number × Positive Number = Negative Number


Positive Number × Positive Number = Positive Number


The cube of -10 can be written as follows:


-10 × -10 × -10


100 × -10


= -1000


Hence (-10)3 = -1000
