Since the circumference of the the circle is 385 and C= 3.14 x D(iameter), you'll have to divide the circumference and 3.14, which is 122.6
Answer:
5^8
----------- which is choice A
4^4
Step-by-step explanation:
(5^2/4)^4
We can separate this (a/b) ^c = a^c / b^c
5^2^5
-------------
4^4
We know that a^b^c = a^(b*c)
5^(2*4)
------------
4^4
5^8
-----------
4^4
Count up the exponents.
6xy
Both 'x' and 'y' have exponents of 1.
1 + 1 = 2
So this is a 2nd degree monomial.
