Simplify. Your answer should contain only positive exponents.

Step-by-step explanation:

It's already in a form that only ha positive exponents.  Just to state it though you could rewrite it as or  The question asks for positive exponents though so yu don't need to do that.

You also need to know so in this case

so

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
