Here is your equation:
![a^{4} \times a](https://tex.z-dn.net/?f=%20a%5E%7B4%7D%20%5Ctimes%20a%20)
First simplify the exponent.
![a^{4} = a \times a \times a \times a](https://tex.z-dn.net/?f=%20a%5E%7B4%7D%20%3D%20a%20%5Ctimes%20a%20%5Ctimes%20a%20%5Ctimes%20a%20%20)
Since the power is 4, you multiply a 4 times. Don't forget about the remaining a. Add that and it becomes:
![a \times a \times a \times a \times a](https://tex.z-dn.net/?f=%20a%20%5Ctimes%20a%20%5Ctimes%20a%20%5Ctimes%20a%20%5Ctimes%20a%20)
It is the same as
because you're multiplying 5 a's. That's why the power is 5.
Your answer is

Step-by-step explanation:
The time taken for the smaller pipe to fill the pool by itself is 15.71 hours
<h3>Rate of work</h3>
- Time taken for both pipes = 6 hours
- Time taken for long pipe = x
- Time taken for small pipe = x + 6
- Rate of work of both pipes = 1/6
- Rate of work of long pipe = 1/x
- Rate of work of small pipe = 1/x + 6
1/6 = 1/x + 1/(x+6)
1/6 = (x+6)+(x) / (x)(x+6)
1/6 = (x+6+x) / x²+6x
1/6 = (2x+6)(x² + 6x)
1(x² + 6x) = 6(2x+6)
x² + 6x = 12x + 36
x² + 6x - 12x - 36 = 0
x² - 6x - 36 = 0
x = 9.71 or -3.71
The value of x cannot be negative
Therefore, the
Time taken for long pipe = x
= 9.71 hours
Time taken for small pipe = x + 6
= 9.71 + 6
= 15.71 hours

The answer to the solution of this system of equations is (7, -4)
Answer:
The standard form of the parabola y = x² + 6x + 62
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that the parabola equation in vertex form
y = ( x+3)² + 53
y = x² + 6 x + 9 +53
y = x² + 6x + 62
The standard form of the parabola y = a x ² + b x + c
The standard form of the parabola y = x² + 6x + 62
