Answer 2

Answer :

Answer 1. is 2520.

Answer 2. is -b/a

Step-by-step explanation:

Answer 1.

The least number divisible by all the number from 1 to 10 will be the L.C.M of following number,

1 = 1

2 = 2 × 1  

3 = 3 × 1

4 = 2 × 2

5 = 5 × 1

6 = 2 × 3  

7 = 7 × 1  

8 = 2 × 2 × 2

9 = 3 × 3

10 = 2 × 5

So, the L.C.M. of these number is 1 × 2 × 2 × 2 × 3 × 3 × 5 × 7 = 2520

Hence, the least number divisible by all the numbers from 1 to 10 is 2520.

Answer 2.

⇒ p(x) = ax + b

⇒ ax + b = 0

⇒ ax = -b

⇒ x = -b/a

Verification of zero :

Put the value of x = -b/a in ax + b = 0

⇒ a (-b/a) + b = 0

⇒ -ba/a + b = 0

⇒ -b + b = 0

⇒ 0 = 0

⇒ LHS = RHS
