( a2 ) ( a2+1 )
4 pieces of A4 fit on one piece of A2.
4 roughly
A4*2 = A3 A3*2 = A2 = 2*2*A4 A2*2 = A1 = 2*2*2*A4 = 8*A4 Answer: 8 pieces of A4 zized papers will fit on 1 sheet of A1.
Here a1 = -6, a2 = -1, a3 = 4 & a4 = 9 d = a2-a1 = -1-(-6) = -1+6 = 5 d = a3-a2 = 4-(-1) = 4+1 = 5 d = a4-a3 = 9-4 = 5 Therefore the common difference d = 5
(a^2 + 8b)(a^2 - 5b)
(a2+2b2-2ab)(a2+2b2+2ab)
While there are many ways of doing it, the simplest way is to use the SUM function and a range in it like this: =SUM(A1:A5)
Excel formulas that will find the average of cells A1, A2, and A4 are: =AVERAGE(A1 ,A2, A4) or =AVERAGE(A1:A2, A4)
an a2 has 6 pieces of a4
4 pieces of A4 fit on one piece of A2.
A2 is the biggest then A4 then A1
Usually simple substitutions enable such expressions to be seen as quadratic expressions. The substitutions x = a2 and y = b2 give a4 + b4 - 7a2b2 = x2 - 7xy + y2 which does not have any rational factors. Consequently, the quartic in a and b does not have rational factors.

At most n-1. However, it can be a lot fewer. For example, calculating A10 does not require 9 multiplications. A*A = A2 A2*A2 = A4 A4*A4 = A8 A8*A2 = A10 Only 4 multiplications were required.
If you mean a2 x a2... the answer is a4
