Given a x B = 6, ab = 4, find a squared B x 3A squared B squared AB squared,

Given a x B = 6, ab = 4, find a squared B x 3A squared B squared AB squared,

a²b+3a²b²+ab²
=ab×（a+3ab+b）
=4×（6+3×4）
=4×18
=72

Finding the number of 3 to the power of 2005
fast

The first power of 3 is 3
The power of two is nine
The third power is 7
The fourth power is 1
It's a cycle
So 2005 / 4 = 501.1
That is to say, the power of 3 is 3

A plus B plus C equals 33, a plus a plus B, a plus B minus C equals 9, find the value of a, B, C
A plus a plus B is 31

Yang Huilin happy
Let a be x, B be (9-2x), C be (x + 9-2x + 9)
Then: x + (9-2x) + (x + 9-2x + 9) = 33
The solution is: x = - 2
∴a=-3
b=9-2x=15
c=x+9-2x+9=21

A of 2A plus B minus the square of 2A plus 2 ab

A of 2A plus B minus the square of 2A plus 2 ab
=(a+b)/(2a)-(2a²+2ab)/(2a)
=(a+b)(1-2a)/(2a)
If you don't understand this question, you can ask,

The diameter of the bottom surface of a cylinder is 2cm and the height is 10cm. What is the surface area of the cylinder;?

Hello
Bottom area = 3.14 × (2 △ 2) &# 178; = 3.14 (square centimeter)
Side area = 3.14 × 2 × 10 = 62.8 (cm2)
Surface area = 62.8 + 3.14 × 2 = 69.08 (cm2)

A = AB, B = ca. (ABC is a different prime number), the greatest common divisor of a and B is (), and the least common multiple is ()?

∵（b,c）=1
(AB, AC) = a, and the least common multiple is ABC
