(1): "*-8" was replaced by "*(-8)". 1 more similar replacement(s)
Step 1 :
1.1 Negative number raised to an even power is positive
For example let's look at (-7)6 , where (-7) , a negative number, is raised to 6 , an even exponent :
(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)
Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.
We proved that (-7)6 is equal to (7)6 which is a positive number
Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 6 by any even exponent, we proved which had to be proved
1.2 8 = 23 (-8)2 = (23)2 = 26
Equation at the end of step 1 :
(8 • (-12)) - (6 • 26)
Step 2 :
Negative Number raised to an Even Exponent :
2.1 21 multiplied by 26 = 2(1 + 6) = 27
Equation at the end of step 2 :
(8 • (-12)) - (27•3)
Step 3 :
Final result :
-376
