Answer:
a non repeating or non terminating decimal but not as a fraction, the decimal goes on forever without repeating.
EXAMPLES: Phi, pi and the square root of any prime number are irrational numbers.
Step-by-step explanation:
The value of y = x(r -1)
Given expression is : <span>x+y-xr
Now, on rearranging the terms of the expression we get,
x -xr + y
Now, we put it equal to zero to find the value:
</span>x -xr + y = 0
⇒ y = xr -x (The signs changes on moving from left-hand side of the equation to the right hand side)
⇒ y = x(r -1)
Answer:
-1.44285714286
Step-by-step explanation:
Answer:
(a) |ab| if a<0 and b>0
since the modulus of a number no matter whether it is positive or negative gives the result as a positive number.
if a<0 and b>0 then ab<0
this implies ab is a negative number and modulus of negative number comes out to be positive term.
<em>eg:</em> if a= -2 and b=3
Then ab= -6
and |ab|=|-6|=6
(b) |ab| if a>0 and b>0.
since both a and b are positive numbers i.e. strictly greater than zero.
hence, ab>0
eg: if a=5 and b=2
then ab=10
and |ab|=|10|=10
