Hello!
The answer are:
- Product of powers.
- Power of a power.
- Negative exponents.
<h2>Why?</h2>
Let's solve it!
It's a math rule that we must solve first what's into a brake or parenthesis, so,
First: Product of powers ![[(7)^{5}*(7)^{3}]](https://tex.z-dn.net/?f=%5B%287%29%5E%7B5%7D%2A%287%29%5E%7B3%7D%5D)
According to the exponent's law, we have a product of powers case, so, we need to sum the exponents and keep the base
Exponents: 5 and 3
Base: 7
Applying it we have:
Then,
We have a power of a power case, which involves multiplying the exponents:
![[(7)^{5}*(7)^{3}]^{-4}](https://tex.z-dn.net/?f=%5B%287%29%5E%7B5%7D%2A%287%29%5E%7B3%7D%5D%5E%7B-4%7D)
Exponents: 3 and -4
Then,
Finally, we can apply the negative exponents, the negative exponent's rules state that negative exponents are the reciprocal of the positive exponents,
So, we will have that:
Have a nice day!
Answer:
Yes, you are right.........
Step-by-step explanation:
Let each let of chicken be C and dog be D respectively.
Then as per question
2C+4D = 28.......i
and
C-D =14........ii
These are the two algebraic equation which you are looking for solve them
to get the answer
Answer:
I think the correct answer from the choices listed above is the last option. The range of the rejected bags, x, for the bags of flour. A bag of flour is said to weigh within 3.2 grams in order to be accepted. Therefore, it should weigh within 746.8 to 753.2 grams. Outside that range is rejected.
Step-by-step explanation:
Responder:
Escala uno
0,2 m
Los 0.067m
Explicación paso a paso:
Dado que :
Escala uno = 1: 1000
Escala dos = 1: 3000
La escala 1 tendrá una vista más detallada porque el dibujo en la escala 1 será tres rublos más grande que el dibujo producido con la escala 2. Por lo tanto, la escala más grande debería tener una vista más detallada.
Un lago de 200 m de largo en realidad:
Tamaño del lago según escala 1
1 = 1000
x = 200
Cruz multiplicar
1000x = 200
x = 200/1000
x = 0,2 m
Según escala 2:
1 = 3000
x = 200
3000x = 200
x = 200/3000
x = 0,067 m
