Answer:
Step-by-step explanation:
Let's first look at the coefficients: 10, -15, 20
The GCF of these numbers is 5 (all numbers are divisible by 5, nothing larger).
Next, let's look at the
terms: ![x^{3}, x^{4}, x^{5}](https://tex.z-dn.net/?f=x%5E%7B3%7D%2C%20x%5E%7B4%7D%2C%20x%5E%7B5%7D)
The GCF of these terms is
(find the lowest exponent)
Finally, let's look at the
terms: ![y^{5}, y^{8}, y^{6}](https://tex.z-dn.net/?f=y%5E%7B5%7D%2C%20y%5E%7B8%7D%2C%20y%5E%7B6%7D)
The GCF of these terms is
(find the lowest exponent)
This gives us a GCF of ![5x^{3}y^{5}](https://tex.z-dn.net/?f=5x%5E%7B3%7Dy%5E%7B5%7D)
<span>In the decimal system, the digits have a position value. In a number of two digits, the digit to the right is in the unis position and its value is the same value of the digit, while the number to the left has a position value of ten times the value of the digit. So the value of 5 y 58 is 5*10 = 50. Answer: 50.</span>
Answer:
![\large\boxed{\log_84a\left(\dfrac{b-4}{c^4}\right)=\log_84+\log_8a+\log_8(b-4)-4\log_8c}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Clog_84a%5Cleft%28%5Cdfrac%7Bb-4%7D%7Bc%5E4%7D%5Cright%29%3D%5Clog_84%2B%5Clog_8a%2B%5Clog_8%28b-4%29-4%5Clog_8c%7D)
Step-by-step explanation:
![\text{Use}\\\\\log_ab^n=n\log_ab\\\\\log_a(bc)=\log_ab+\log_ac\\\\\log_a\left(\dfrac{b}c{}\right)=\log_ab-\log_ac\\\\==============================](https://tex.z-dn.net/?f=%5Ctext%7BUse%7D%5C%5C%5C%5C%5Clog_ab%5En%3Dn%5Clog_ab%5C%5C%5C%5C%5Clog_a%28bc%29%3D%5Clog_ab%2B%5Clog_ac%5C%5C%5C%5C%5Clog_a%5Cleft%28%5Cdfrac%7Bb%7Dc%7B%7D%5Cright%29%3D%5Clog_ab-%5Clog_ac%5C%5C%5C%5C%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D)

The answer is 8x-1 I believe
Only one time...............
