that will be 2130,1
Step-by-step explanation:
Answer:
2×2×3×3×3
Step-by-step explanation:
●108=
•2×54
•2×27
•3×9
• 3×3
Writing the prime numbers;
108=2×2×3×3×3
Here we are required to rewrite the equation ax-by=c, where a,b,c>0 In the slope-intercept form.
The slope-intercept form of ax-by=c is ;
y = (a/b)x - (c/b).
There a no. of ways to write the equation of a line; however, the most popular of these ways is the slope-intercept form.
- The slope-intercept form usually takes the form ; y = mx + c.
Therefore, the equation ax-by=c can be rewritten thus;
- ax - c = by
- By divIDing both sides of the equation by b, we have ;
- (a/b)x - (c/b) = y
Consequently, the slope-intercept form of ax-by=c is ;
- y = (a/b)x - (c/b).
- where , (a/b) is the slope(m)
- and (-c/b) is the intercept(c).

ANSWER
![3 \sqrt{7}](https://tex.z-dn.net/?f=3%20%5Csqrt%7B7%7D%20)
EXPLANATION
The given radical is
![7 \sqrt{7} - 2 \sqrt{28}](https://tex.z-dn.net/?f=7%20%5Csqrt%7B7%7D%20%20-%202%20%5Csqrt%7B28%7D%20)
Remove the perfect square from the second radical.
![= 7 \sqrt{7} - 2 \sqrt{4 \times 7}](https://tex.z-dn.net/?f=%20%3D%207%20%5Csqrt%7B7%7D%20%20-%202%20%5Csqrt%7B4%20%5Ctimes%207%7D%20)
![= 7 \sqrt{7} - 2 \sqrt{4} \times \sqrt{7}](https://tex.z-dn.net/?f=%20%3D%207%20%5Csqrt%7B7%7D%20%20-%202%20%5Csqrt%7B4%7D%20%20%5Ctimes%20%20%5Csqrt%7B7%7D%20)
![= 7 \sqrt{7} - 2 \times 2 \times \sqrt{7}](https://tex.z-dn.net/?f=%20%3D%207%20%5Csqrt%7B7%7D%20%20-%202%20%20%5Ctimes%202%20%5Ctimes%20%20%5Csqrt%7B7%7D%20)
![= 7 \sqrt{7} - 4 \sqrt{7}](https://tex.z-dn.net/?f=%20%3D%207%20%5Csqrt%7B7%7D%20%20-%204%20%5Csqrt%7B7%7D%20)
Subtract the like radicals
![= 3 \sqrt{7}](https://tex.z-dn.net/?f=%20%3D%203%20%5Csqrt%7B7%7D%20)
