Answer:

1856

Step-by-step explanation:

The numbers given do not have a common difference, but they do have a common ratio:

58/29 = 116/58 = 2

The general term of a geometric sequence with first term a1 and common ratio r is ...

an = a1×r^(n-1)

For this sequence, a1=29 and r=2, so the general term is ...

an = 29×2^(n-1)

Then the 7th term is ...

a7 = 29×2^(7-1) = 29×64 = 1856

The 7th term is 1856.

_____

If you prefer, you can double each term until you have 7 of them.

29, 58, 116, 232, 464, 928, 1856, ...

Answer:

f(x) - g(x) = -x⁸ + 8x³ + 5x² - 13

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra I

Combining like terms

Step-by-step explanation:

Step 1: Define

f(x) = -5x⁹ - x⁸ + 3x³ - 8

g(x) = -5x⁹ - 5x³ - 5x² + 5

Step 2: Find f(x) - g(x)

Substitute: f(x) - g(x) = -5x⁹ - x⁸ + 3x³ - 8 - (-5x⁹ - 5x³ - 5x² + 5)
Distribute -1: f(x) - g(x) = -5x⁹ - x⁸ + 3x³ - 8 + 5x⁹ + 5x³ + 5x² - 5
CBT (x⁹): f(x) - g(x) = -x⁸ + 3x³ - 8 + 5x³ + 5x² - 5
CBT (x³): f(x) - g(x) = -x⁸ + 8x³ - 8 + 5x² - 5
CBT (Z): f(x) - g(x) = -x⁸ + 8x³ + 5x² - 13

And we have our final answer!

Answer:

$\large\boxed{(n^3)^2\times(n^5)^4=n^{26}}$

Step-by-step explanation:

$(n^3)^2\times(n^5)^4\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=(n^{3\cdot2})\times(n^{5\cdot4})=n^{6}\times n^{20}\qquad\text{use}\ a^n\times a^m=a^{n+m}\\\\=n^{6+20}=n^{26}$
