What do the zero exponent and negative exponents properties mean

In other words, if you raise a nonzero number to the power of
0
,
the result is
1.

Mathematicians debate the value of

0

Some say it's
1
,
and some say it's undefined.

Here are some examples of the Zero Power Rule. Notice it works for numbers and for variables.

Why does the Zero Power Rule hold? Here's one way to think about it:

Then, by the quotient rule for exponents, we can write this as:

Then this becomes a problem about dividing fractions. Since the numerator and the denominator are both the same this becomes

Which values of a, b, and c correctly complete the division? One-fourth divided by StartFraction 5 Over 6 EndFraction = StartFraction 1 Over a EndFraction times StartFraction b Over c EndFraction a = 4, b = 5, c = 6 a = 1, b = 6, c = 5 a = 1, b = 5, c = 6 a = 4, b = 6, c = 5

Answers

Answer:

a = 4, b = 6 and c = 5

Step-by-step explanation:

It is given that,

[tex]\dfrac{\dfrac{1}{4}}{\dfrac{5}{6}}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]

We know that,

[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

So,

[tex]\dfrac{1}{4}\times \dfrac{6}{5}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]

If we compare both sides of the equation we get,

a = 4, b = 6 and c = 5

Hence, these are the values of a,b and c.

how to solve this 58+5x+10=11x+2

Answers

Answer:

11 = x

Step-by-step explanation:

58+5x+10 = 11x+2

68+5x = 11x+2

-5x = -5x

68 = 6x+2

-2 -2

66 = 6x

66/6 = 6x/6

11 = x

Hope this helps!

Answer:

x = 11

Step-by-step explanation:

58 + 5x + 10 = 11x + 2

First, combine like terms

68 + 5x = 11x + 2

Subtract 5x from both sides of the equation

68 = 6x + 2

Subtract 2 from both sides of the equatino

66 = 6x

Divide both sides by six to get your answer

11 = x

It takes 66 pounds of seed to completely plant a 7-acre field.
How many acres can be planted per pound of seed?
acres per pound

Answers

Answer:

Approximately 0.11 acres can be planted with one pound of seed

Step-by-step explanation:

You use the rule of 3

66 pounds / 7 acres = ? pounds / 1 acre

? = 66 x 1 ÷ 7

? = 66 ÷ 7

? ≈ 9.23 pounds / acre

Now you know how many pounds you have for 1 acre. You reuse the formula from before

9.23 pounds / 1 acre = 1 pound/ ? acres

? = 1x1 ÷ 9.23

? = 1 ÷ 9.23

? = 0.11 acres/pound

Verify the answer:

0.11 x 9.23 ≈ 9.33, which is approximately 1 pound

Answer:

90 pounds per acre

2x+2a=4b solve for a

Answers

Answer:

a=2b-x

Step-by-step explanation:

Simplifying
2x + 2a = 4b

Reorder the terms:
2a + 2x = 4b

Solving
2a + 2x = 4b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2x' to each side of the equation.
2a + 2x + -2x = 4b + -2x

Combine like terms: 2x + -2x = 0
2a + 0 = 4b + -2x
2a = 4b + -2x

Divide each side by '2'.
a = 2b + -1x

Simplifying
a = 2b + -1x

Answer: x=1

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3*x+2*(5*x-3)-(7)=0

3x + 2 • (5x - 3)) - 7 = 0

Pull out like factors :

13x - 13 = 13 • (x - 1)

13 = 0

A a non-zero constant never equals zero.

Solve : x-1 = 0

Add 1 to both sides of the equation :
