Example Question #1 : Other Pre Algebra Properties
Simplify.
Since the two powers are not of the same base, we cannot combine the exponents.
We cannot simplify the equation further.
Example Question #2 : Other Pre Algebra Properties
Simplify.
The first part is .
One way to simplify this portion is to apply the distributive property twice to get:
By the commutative property of multiplication , so the two middle terms cancel out (one is positive and the other negative, resulting in zero).
This leaves .
Note: the identity is worth memorizing, because it is very useful in higher math. The same result can be achieved by using FOIL.
Returning to our original expression, we can substitute:
Now, apply the distributive property to the second part of the expression:
Combining everything together:
Use the associative property of addition to group like terms and simplify.
Example Question #3 : Other Pre Algebra Properties
