Question

write down the degree of the following terms
1) -8x square 6
2) 7
3) 2x square 2
4) -x square 5
5) 6x​
​

Answer 1

Answer:

Given : integers from 1 to 300 which are divisible by 2 or 5​

To find : Sum of integers

Solution :

integers from 1 to 300

Divisible by 2  

2 , 4  , 6  , .........................................., 300

Sum

= 2+ 4  + 6  + .........................................+300

= 2(1 + 2 + 3 +.............................+ 150)

= 2 ( 150)(151)/2

= 22650

Divisible by 5

5 , 10  , 15  , .........................................., 300

Sum

= 5+ 10 + 15  + .........................................+300

= 5(1 + 2 + 3 +.............................+ 60)

= 5 (60)(61)/2

= 9150

Both contains number divisible by 10

Divisible by 10

 10  , 20  , .........................................., 300

Sum

=   10 +20  + .........................................+300

= 10(1 + 2 + 3 +.............................+ 30)

= 10 (30)(31)/2

= 4650

sum of integers from 1 to 300 which are divisible by 2 or 5​

= 22650 + 9150 - 4650

=27150

27150  is   sum of integers from 1 to 300 which are divisible by 2 or 5​
