For this case we must find the quotient of the following expression:
We can rewrite the expression as:
(We take into account that)
By definition of multiplication of powers of the same base, we place the same base and add the exponents:
By definition of division of powers of the same base, we place the same base and subtract the exponents:
Answer:
Answer:(1) The correct option is b. (2) The correct option is c.
Explanation:
(1)
It is given that the △ABD≅△FEC.
So by (CPCTC) corresponding parts of congruent triangles are congruent.
It is given that the angle DAB is 63 degree.
Therefore, the correct option is b.
(2)
It is given that the △ABD≅△FEC.
So by (CPCTC) corresponding parts of congruent triangles are congruent.
Therefore, the correct option is c.
