Commutative Property of Addition
a + b = b + a
Commutative Property of Multiplication
a • b = b • a
Associative Property of Addition
a + ( b + c ) = ( a + b ) + c
Associative Property of Multiplication
a • ( b • c ) = ( a • b ) • c
Distributive Property
a • ( b + c ) = a • b + a • c
Additive Identity Property
a + 0 = a
Multiplicative Identity Property
a • 1 = a
Additive Inverse Property
a + ( -a ) = 0
Multiplicative Inverse Property
a * (1/a) = 1
Note: a cannot = 0
Zero Property
a • 0 = 0
Add: [2^(1/3)] + [5^(1/3)]
7^(1/3)
5^(1/3) + 2^(1/75)
1. Are the radicals the same? Answer
: NO
2. Can we simplify either radical?
Answer
: Yes, 2^(1/75) can be simplified.
3. Simplify the radical.
Answer
:
2^(1/75)
2^(1/25)*(1/3)
2*5 + 2^(1/3)
10 + 2^(1/3)
4. Now, the radicals are the
same and we can add.
10 + 2^(1/3) + 5^(1/3)
Answer:
10 + 7^(1/3)
