Explain how the Quotient of Powers Property was used to simplify this expression.

1 answer:
Strike441 [17]3 years ago

Answer:

\frac{5^{4}}{25} = 25

Step-by-step explanation:

I'm not sure if you had a typographical error with this statement, "5 to the fourth power, over 25 = 52."

According to the <u>Quotient Rule of Exponents</u><u>:</u>

\frac{a^{m}}{a^{n}} = a^{(m-n)}

Method 1:

In order for you apply the Quotient Rule, the base must be the same. Since 5 is a factor of 25, then you could rewrite 25 as 5². Doing so will give you the following exponential expression:

\frac{5^{4}}{5^{2}} = 5^{(4 - 2)} = 5^{2} = 25

Method 2:

Even if you solve the given problem manually, you'd still get the same answer:

\frac{5^{4}}{25} = \frac{5*5*5*5}{25} = \frac{625}{25} = 25

Both methods produced the same result, proving that the correct answer is 25.

find the two angle measures from the diagram 3x+10 3x-28 there's 3 answer's 71,71 109 ,109 109,71 last question brainiest u will
andriy [413]

Answer:

<h2>109 and 71</h2>

Step-by-step explanation:

3x + 10 + 3x - 28 = 180

6x = 180 - 10 + 28

x = 198/6

x = 33

substitute the value of x = 33 back into the equation to solve for each angle

= 3x + 10

= 3(33) + 10

= 109

= 3x - 28

= 3(33) - 28

= 71

100 is 1/10 of what?
lawyer [7]

\boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<h3>Further explanation  </h3>

The question can be rewritten to \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ M \ }  

This case about equations with one variable. We have to solve this calculation to obtain the value of M. Our task is to isolate the variable M alone at the end of the process on one side of the equation until the variable will be equal to a value on the opposing side.  

Let's arrange it into an equation, i.e., \boxed{ \ 100 \ = \ \frac{1}{10} \times \ M \ }  

Turn this equation over so that the position of variable M is on the left side.  

\boxed{ \ M \times \frac{1}{10} = 100 \ }  

Both sides are multiplied by 10 to isolate M on the left side. The fraction are eliminated.  

\boxed{ \ M \times \frac{1}{10} \times 10 = 100 \times 10 \ }  

M = 1,000  

Therefore, we have calculated the number that was asked.  

Hence \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<u>Note:  </u>

The significant thing to carry out is how to manipulate both sides of the equation with the algebraic properties of equality such as:  

  • Adding  
  • Subtracting  
  • Multiplying, and/or  
  • Dividing both sides of the equation with a similar number

And the commutative property of multiplication, i.e., \boxed{ \ a \times b = b \times a \ }

If a certain canon is fired from a height of 8.9 m above the ground, at a certain angle, the height of the Campbell above the gr
qwelly [4]

Answer:

T=5.9235 seconds

Step-by-step explanation:

H(T)= -4.9T^2+27.52T+8.9.

The time it takes for the cannonball to strike the ground is the point at which H(T)=0

H(T)= -4.9T^2+27.52T+8.9.=0

-4.9T^2+27.52T+8.9=0

This is a quadratic equation and since we have a bunch of decimals we use the quadratic formula:

x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}

a=-4,9, b=27.52, c=8.9

T=\dfrac{-27.52\pm\sqrt{(-27.52)^2-(4*-4.9*8.9)} }{2*-4.9}\\=\dfrac{-27.52\pm\sqrt{757.3504-(-174.44)} }{-9.8}\\=\dfrac{-27.52\pm\sqrt{931.7904} }{-9.8}\\=\dfrac{-27.52\pm30.53 }{-9.8}\\T=-0.3071 \:or\:  5.9235\\T=5.9235 seconds

It takes 5.9235 seconds for the cannonball to strike the ground.
