There are many theories and measurement for the speed of light. It is believed that light travels at 299,792 km per second.  In the earlier day philosopher Aristotle believed that light didn't travel but happens instantaneously.  Therefore, for Galileo and his assistant to be only 1km apart, I would have to agree with Aristotle theory of light traveling instantaneously.

Convert to the product of multiplication<br>a^2-b^2-4b-4
kirill [66]

a^2-b^2-4b-4 in form of multiplication is  (a-b)(a+b)-4(b+1) .

<u>Step-by-step explanation:</u>

We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .

Here , we need to convert to the product of multiplication

a^2-b^2-4b-4 or , a^2-b^2-4b-4 :

⇒  a^2-b^2-4b-4

We know by identity that , p^2-q^2 = (p-q)(p+q)

⇒  (a-b)(a+b)-4b-4

Taking common term out as -4 :

⇒  (a-b)(a+b)-4(b+1)

Therefore  , a^2-b^2-4b-4 in form of multiplication is  (a-b)(a+b)-4(b+1) .
