Answer 1

Step-by-step explanation:

A shooting star is another name for a meteoroid that burns up as it passes through the Earth's atmosphere. So, a shooting star isn't a star at all. Most of the shooting stars that we can see are known as meteoroids. ... When a meteoroid is larger, the streak in the sky is called a fireball or bolide.2

Answer 2

SOLUTION

Consider,

107 × 103 = (100 + 7)(100 + 3)

Here we use the identity

(x + a)(x + b) = x² + (a+b) × ab

Taking,

x = 100, a = 7 and b = 3

We get,

107 × 103 = (100 + 7)(100 + 3)

= 100² + (7+3) 100 + 7×3

= 10000 + 1000 + 21

= 11021

Hence,

107 × 103 = 11021.
