Answer:
I don't know am answering fr my pts sry
1) (b) 13915
(2) (c) 11
3) (b) 23
4) a composite number
5) 5 × 11² × 23
Step-by-step explanation:
1) What will be the value of x?
X
↓ ↓
5 2784.
When we find the value of tree method we multiple the given vale
5 × 2783 = ?
13915
2) what will be the value of y?
2783
↓ ↓
Y 253
When we find the y value, we get
which term is multiple by 253
EG:
2 × 253 = 506
10 × 253 = 2530
11 × 253 = 2783.
253 × 11
253
253*
2783
= 11
3) find the value of z?
253
↓ ↓
11 2
In the table of 11,which number is multiple by 11 the we find the value of 253.
11 × 5 = 55
11 × 20 = 220
11 × 23 = 253
33
23*
253
b() 23
4) According to fundamental theorem of arithmetic 13915 is a
13915 5 × 2783
Since 13915 has factors other than 1 and the number itself
It is a composite number
So, correct answer is (A).
5) prime factorization of 13915 is?
By Factor tree,
253
13915 = 5 × 2783
n = 5 × 253 × 11
= 5 × 11 × 23 × 11
= 5 × 11² × 23
it's a correct answer ( 5 × 11² × 23).
