( a2 ) ( a2+1 )
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.
no . A3 is bigger than A4 .
An A4 page is too large to fit into an A5 page, as A4 is twice as large than A5. An A5 page would fit into an A4 page twice.
4 pieces of A4 fit on one piece of A2.
( a2 ) ( a2+1 )
To factor a^4 - b^4 completely, you can use the formula for the difference of squares, which states that a^2 - b^2 = (a + b)(a - b). In this case, a^4 - b^4 is a difference of squares twice: (a^2)^2 - (b^2)^2. So, you can factor it as (a^2 + b^2)(a^2 - b^2). Then, factor a^2 - b^2 further using the difference of squares formula to get (a^2 + b^2)(a + b)(a - b), which is the complete factorization of a^4 - b^4.
(a2+2b2-2ab)(a2+2b2+2ab)
That looks simple enough for me; but if you want to factor it, you can use the formula for the difference of two squares.
a5+b5 = (a+b) (a4-a3b+a2b2-ab3+b4)
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.
no . A3 is bigger than A4 .
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.

Half of A4 is A5.
