It is also the same as 8 to the power of 7
which looks something like this 8^7
you can also do it by doing 64×64×64×8
then do 64×64
multiply that answer by 64
multiply that answer by 8
this will work with any question and you can do it without a calculator and on paper.
It is the same as what you had said and so a rational number is the same thing as a rational number and nothing changes.
Answer:
11
Step-by-step explanation:
d=√(5-(-6))²+(-7-(-7))²
d=√(11²+0²)
d=11
Answer:
(x-1)²+(y-3)²=65
Step-by-step explanation:
the common view of the equation of a circle is:
a) (x-a)²+(y-b)²=r², where (a;b) - the centre of the required circle, r - the radius of the required circle;
b) using the coordinates of the endpoint of the given diameter it is possible to calculate the coordinates of the centre of the required circle and its radius²:
the coordinate x of the required circle is: (9-7)/2=1;
the coordinate y of the required circle is: (2+4)/2=3.
the radius² of the required circle is:
r²=0.25*[(9- -7)²+(2-4)²]=0.25*260=65.
c) after the substitution the values of 'a'; 'b' and 'r²' into the common equation of the circle:
(x-1)²+(y-3)²=65.
PS. additional: the given points (9;2) and (-7;4) belong to the final equation, if to substitute their coordinates into it.
The suggested way of solution is not the only one.
