Answer:
3.14*6.5^2*16=
42.25*16=2122.64 or 2122.6
Step-by-step explanation:
Answer:
-68 is not a term in the given sequence
Step-by-step explanation:
The given sequence is -12, -17, -22, -27...
There is a common difference of d=-17--12=-5
The explicit rule for this sequence is 
Or 
To find the term that has a value of -68 we equate the explicit formula and solve for n.




The position should be a natural number.
Since n is a decimal, it tells us that -68 is not a term in the given sequence
Answer:
a=3
b=3
Step-by-step explanation:
(2xy)^4
----------------
4xy
Expand the numerator
2^4 x^4 y^4
---------------------
4xy
Simplify
16 x^4 y^4
---------------------
4xy
We know that a^b / a^c = a^(b-c)
16/4 * x^(4-1) y^(4-1)
4 x^3 y^3
