The greatest common factor (GCF) of x^3, x^7, x^9 is ?<br> Please help

solong [7]

Answer:

$x^3$

Step-by-step explanation:

Let the greatest common factor of $a,b,c$ such that $a,b,c \in\mathbb{Z}$ and they are not all equal to zero, $d$ is the common divisor of $a$ and $b$ . Therefore, $d \mid a$ and $d \mid b$

You can write

$D(a) = \{d \in\mathbb{Z} : d \mid a\}$

$D(b) = \{d \in\mathbb{Z} : d \mid b\}$

The greatest common factor of $a,b$ is given as

$D(a,b) = \{d \in\mathbb{Z} : d \mid a \text{ and } d \mid b\}$

and

$D(a, b) = D(a) \cap D(b)$

This happens because $D(a,b)$ is upper bounded because if $a\neq 0$ then $d \leq |a|$

for all $d\in D(a, b)$ . Therefore, the set $D(a, b)$ has the greatest elements.

Taking $x^3, x^7, x^9$ such that $x>0$

You can note that $x^7 = x^3 \cdot x^4$ and $x^9 = x^3 \cdot x^6 = x^3 \cdot x^3 \cdot x^3$

Therefore, the greatest common factor is $x^3$

Note: $x^3 \cap x^7 \cap x^9 = x^3$

Alexus [3.1K]

Answer:

7(n - 6)

(2 - x)

Step-by-step explanation:

2 - x is the base and 7(n - 6) the exponent.

The desired expression is:

7(n - 6)

(2 - x)

or

(2 - x) ^ (7(n - 6))

Find the solution(s) to 7x - 42x = 0. Check all that apply.

blsea [12.9K]

Answer:

x=0

Step-by-step explanation:

7x - 42x = 0

Combine like terms

-35x = 0

Divide each side by -35

-35x/-35 = 0/-35

x = 0
