Given a + B = 2, ab = 3, find 1A ^ 3b of 2 + A ^ 2B ^ 2 + 1ab ^ 3 of 2

Given a + B = 2, ab = 3, find 1A ^ 3b of 2 + A ^ 2B ^ 2 + 1ab ^ 3 of 2

（1/2）a^3b+a^2b^2+(1/2)ab^3
=1/2ab(a^2+2ab+b^2)
=1/2ab(a+b)^2
=1/2×3×2^2
=6

If x = - 1 / 3, y = 3 is, find the value of the following algebraic expression
(1) The square of 3x - the square of 2Y + 1
(2) The square of XY-1 (X-Y)

(1) The square of 3x - the square of 2Y + 1
=1/3-18+1
=-16 and 2 / 3;
(2) The square of XY-1 (X-Y)
=(-1/3-3)²/(-2)
=-50/9;

Mathematical problems (values of algebraic expressions)
The annual profit of an enterprise in 2005 is 1 million yuan. If the annual profit of the next year is p% higher than that of the previous year, how much is the annual profit in 2006 (to be simplified) million yuan, and how much is the annual profit in 2007 (to be simplified) million yuan. According to this calculation, when p% = 10%, how much is the annual profit in 2008?

2006 100 * (1 + P%)
2007 100 * (1 + P%) * (1 + P%)
2008 100 * (1 + P%) * (1 + P%) * (1 + P%)
When p% = 10%, just change P% to 10%···
