Mathematics (binomial theorem) (523:19:52)
1 it is known that the sum of all coefficients in the expansion of (1 + 2x) n is equal to 729, then the coefficient of X3 term in the expansion is:
A.56  B.80   C.160  D.180
2. The value of the constant term in the (| x | + 1 / | x | - 2) 3 expansion is:
A.-20   B.20   C.-15   D-28

1. Let x = 1,3 ^ n = 729, n = 6
The answer is C

It is known that the sum of the first n terms of the sequence {an} is SN. A1 = 1, an + 1 = 1 / 3Sn (n ∈ & # 160; N +)
1. Find the values of A2, A3 and A4
2. Find the general term formula of sequence an

An = SN-S (n-1) = 3 (an + 1) - 3 [a (n-1) + 1] = 3an-3a (n-1) we can get 2An = 3A (n-1) an = 3A (n-1) / 2. From this we can see that the sequence is an equal ratio sequence with scale coefficient of 3 / 2. Then the common formula of the sequence an is: an = (3 / 2) ^ (n-1) also

What is the minimum number of a number divided by 5, 6 and 7

The least common multiple of 5, 6 and 7 is 5 × 6 × 7 = 210
Then: 210 + 2 = 212
So, the minimum number is 212

1 flat angle=______ Right angle=______ Flat angle=______ Right angle

1 flat angle = 2 right angle 1 circle angle = 2 flat angle = 4 right angle, so the answer is: 2, 2, 4

Definition of right angle, horizontal angle and perimeter angle

A straight line rotating 90 degrees around the origin is called a right angle. A straight line rotating 180 degrees around the origin is called a flat angle
A straight line rotates 360 degrees around the origin, called the circumference
