1) 0,3
2) 1/4
3) 1/3

Автор ответа: sangers1959

(0,1)^(-lg0,3)=(1/10)^(-lg0,3)=10^lg0,3=0,3.
10^(-lg(-4)=1/(10^lg(-4))=1/(-4)=-0,25.
5^(-log₅3)=1/5^(log₅3)=1/3.
(1/6)^(-log₆4)=6^log₆4=4.

A) Newfoundland and Labrador is a province in the East of Canada. It includes the
island of Newfoundland and a region on the mainland of North America called
Labrador. St. John’s, the capital of this Canadian province, is located on
Newfoundland island. Both Labrador and Newfoundland are washed by the
Atlantic Ocean and have mountains.
B) The first Europeans to visit Labrador were the Vikings. Then, in 1497 the
Italian explorer John Cabot landed somewhere in Newfoundland and Labrador
and described the place as the “new found land”. England, France and Portugal
fought for this land, but by the 1700s Newfoundland belonged to England. In
1949 it became the tenth Canadian province.
C) When John Cabot landed on Newfoundland’s coast, he was surprised to see
that the waters around the island were full of fish. This is one of the reasons
why people in this province enjoy eating a lot of fish. Fishcakes, salted cod and
Fish ‘n Brewis are just some of the fish dishes that local people have been
eating for centuries.
D) When foreigners hear the name of this province, they often think of the dog
breeds of the same name – Newfoundland and Labrador. Both dogs originated
in these lands and both were used by fishermen. The huge Newfoundland dogs
are excellent swimmers and often save their owners in the dangerous waters of
the Atlantic. The English poet Lord Byron owned such a dog.

E) Because of the province’s specific geography, the easiest way to get there is
either by plane or by boat. Before airplanes were invented, Newfoundland was
a communications centre. Most ships travelling across the Atlantic to Canada
from Europe arrived there first. It is also the shortest flight across the Atlantic.
The first transatlantic flight was made from St. John’s to Ireland.
