Match the expressions with their equivalent simplified expressions.

for each expression, we will simplify the numerical part as usual, while we will use the following properties to deal with exponents of variables:

rule #1:

rule #2:

rule #3:

first expression:

numeric part:

exponent for a (rule #1):

exponent for b (rule #1):

second expression:

numeric part:

exponent for a (rule #1 + #3):

exponent for b (rule #1):

third expression:

numeric part:

exponent for a (rule #1):

exponent for b (rule #1):

fourth expression:

numeric part:

exponent for a (rule #1 + #2 + #3):

exponent for b (rule #1 + #3):

fifth expression:

numeric part:

exponent for a (rule #1 + #3):

exponent for b (rule #1 + #2):

sixth expression:

numeric part:

exponent for a (rule #1 + #2 + #3):

exponent for b (rule #1 + #3):

step-by-step explanation:

their are no angles. sorry cant .

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
