Объяснение:

a²-6a+9/27-a³= a²-6a+9/(3-a)(9+3a+a²)=(a-3)²/(3-a)×(9+3a+a²)= (3-a)²/(3-a)(9+3a+a²)=3-a/9+3a+a²

Ответ:

\dfrac{a^2-6a+9}{27-a^3}=\dfrac{(a-3)^2}{(3-a)(9+3a+a^2)}=\dfrac{(3-a)^2}{(3-a)(9+3a+a^2)}=\dfrac{3-a}{a^2+3a+9}

The Changing World of Computers

Computers are rapidly changing the way we do things. For a technology that is still relatively new, their A22 ...................... on the business and consumer sector has been incomprehensible. As if it was not sufficient to own one computer, many people nowadays have a few of them. We think we need a desktop computer, a laptop computer, and a bunch of little computers in our phones and music players, even A23 ...................... they actually do the same thing. Now that everybody has their desktops and laptops, and we are all able to A24 ...................... the Internet anytime we want to, our world has turned into a virtual playground. We can now connect with our foreign neighbours in a matter of seconds, A25 ...................... of how far away they are from us. It's as if we no longer have borders in this highly digital world of ours.

Desktops have always been a great option, but the problem with them is that they are not mobile.

But when people have to be connected while travelling, the need for laptops really becomes apparent. The main advantage of laptops is the ability to communicate with people no A27 ...................... where you are. Our society has been converted into one that has to have all the latest gadgets. Some people even A28 ...................... down on others if they still have last year's model of some gadget. Those people will always be behind the curve just because of how fast technology is advancing now.
