Which is larger in magnitude?

5 + n or  5n

This question is compulsory.

1. 5n is definitely larger. 5n= 5*n so it will definitely be larger than 5+n
Thank you~~~
:DD

2. 5n is larger.5n is equal to 5 times of n but 5+n is just 5 more than n e.g 5*5=25 5+5=10. Therefore 5n is larger than 5+n.

3. 5n because 5 + n is adding the digit 5 to the n but 5n is the product of 5 and n

4. 5 n is larger. As 5n=5*n=5 times of n,while 5+n is the sum which 5 is added to n.

5. 5n is larger than 5 + n.
I say this as 5n is 5 times n and 5 + n is 5 added to n.

Eg, if n=2,
5n=5 x 2
=10
5 + n= 5 + 2
=7

6. 5N is larger than 5+N. 5N is 5xN which is 5 sets of N. While 5+N is 1 set of 5 + 5.

Unless N = 1.
If it is equal to 1. 5+N will be equal to 5+1=6.
While 5N will be equal to 5x1=5

7. 5n is larger as 5n= 5*n but 5+n is 5+n. The only case that 5+n is larger is when n is decimal or 0 or negative.
Example 1: (5n is bigger) n is a natural number. ep: 14 so 14*5=70 but 14+5 is 19.

Example 2: (5+n is bigger) n can be anything such as 5n= lesser then 5.Let n=1
1*5=5 5+1=6.

8. 5n is larger as n is multiplied by 5 in 5n rather than 5+ n which is adding 5 to n. So 5n has to be larger.

It depends on the value of n. If n = 1 or 0, then 5 + n will be bigger than 5n. But if the value of n is more than 1, then 5n will be bigger than 5+n.

10. 5 + n or 5n

5+n is smaller as 5n is equal to 5 * n times but 5+n is only 5 and n added together.

11. If n≤1, 5+n would be larger because if n=1, 5+1=6 is larger than 5*1=5, if n=0,5+0=5 is larger than 0*5=0,if n is a negative number n=(-1),5+(-1)=4 which is larger than (-1)*5=(-5).
However, if n>1, 5n would be larger because if n=2,2*5=10 is larger than 5+2=7.

12. When n=5/4, 5+n equal to 5n.

When n >5/4, 5n>5+n.

When n <5/4, 5+n>5n.

13. It depends on the value of n. Eg: If n=0.5, then 5n=0.5*5=2.5 as compared to 5+n=5+0.5=5.5. Thus, over here 5+n is bigger. If n=3, then 5n=3*5=15 as compared to 5+n=3+5=8. Thus, over here 5n is bigger.

14. Assuming n is a natural number larger than 1, 5n will be bigger than 5+n

eg.
5*2=10
5+2=7

15. The term 5n is larger in magnitude.5n is equal to five times of n but 5+n means the addition of 5 and n.

Eg : Let n be 4.

1. 5n=5*4 2. 5+n=5+4
=20 =9

The number 20 is larger than 9 so 5n is larger than 5+n.

16. It depends on the value of n.

If n=0, then 5 + n=5
5n=0
in this case, 5 + n is larger.

If n=1, then 5 + n=6
5n=5
in this case, 5 + n is larger.

If n=2, then 5 + n=7
5n=10
in this case, 5n is larger.

As long as n is ≥2, 5n will always be larger than 5 + n, but if it is less, then 5 + n is larger.

17. 5n is larger.
Assume that n is 4.
5n= 5x4
= 20
5+n= 5+4
=9
OR
Assume n is 20
5n=5x20
= 100
5+n=5+20
=25
So, 5n is larger than 5+n

19. 5n is larger than 5+n.
For 5n, there are 5 times of n. However, for 5+n, it is only n plus 5.

Example:
Let n be 2.
5n=5x2
=10
5+n=5+2
=7

Hence, 5n is larger than 5+n in magnitude
