Choose the correct simplification of the expression a to the 7th power times b to the 8th power all over a to the 4th power times b to the 4th power

Answers

First you need to write the numerical equation for the given:

( a^(7) b^(8) )/( a^(4) b^(4) )

When you will simplify this fraction, you can divide the expressions. Based on the law of exponents when you divide like terms with different exponents, you can subtract the exponents of the denominator from the numerator. 

So if you will simplify the equation:

( a^(7) b^(8) )/( a^(4) b^(4) )

Subtract the following:

Exponents of a 7-4 and;
Exponents of b 8-4

Your answer should be 
a^(3) b^(4)

Four less than the sum of a number and 7 is eight more than twice that number. find the number.

Answers

Answer:

-5

Step-by-step explanation:

To find the number, let's break down the problem step by step.

First, let's assign a variable to represent the unknown number. Let's call it "x."

According to the problem, "four less than the sum of a number and 7" can be written as "(x + 7) - 4."

Next, the problem states that this expression is "eight more than twice that number." So, we can write this as "2x + 8."

Now, we can set up an equation based on the information given:

(x + 7) - 4 = 2x + 8

Let's solve this equation to find the value of x.

First, let's simplify the left side of the equation:

x + 7 - 4 = 2x + 8

x + 3 = 2x + 8

Next, let's isolate the variable by subtracting x from both sides:

x - x + 3 = 2x - x + 8

3 = x + 8

To isolate x, we need to get rid of the 8 by subtracting it from both sides:

3 - 8 = x + 8 - 8

-5 = x

Therefore, the number is -5.

To check our answer, let's substitute -5 into the original equation and see if it holds true:

( -5 + 7) - 4 = 2(-5) + 8

2 - 4 = -10 + 8

-2 = -2

The equation holds true, which confirms that the number is indeed -5.

n-the\ number\n\n7* n+3=38\n7n+3=38\ \ \ \ |subtract\ 3\ from\ both\ sides\n7n=35\ \ \ \ |divide\ both\ sides\ by\ 7\n\n\boxed{n=5}
So,

If we translate this into mathematical form, we get
7n + 3 = 38

Subtract 3 from both sides
7n = 35

Divide both sides by 7
n = 5
