Real numbers are all rational and irrational numbers that exist on the number line. There are infinitely many real numbers, so instead …

See an explanation below: All rational numbers are real numbers. However, all real numbers are not rational numbers. For example: …

None By definition an irrational number is not rational. Rational numbers are real numbers that are expressible in the form p/q for …

Now, we can take logs of both sides: #Log ( (2/3)^ (-x))=Log (-100/27)# Log of a negative number is undefined. There is no solution …

Basically the same as we do with the real numbers. Perhaps if we rewrite this as: (3+2i)* (1-3i) then we mulitply 3 from the first …

Explanation: #f (x)# = # (sqrt (x+1))/ (x^2-9)# Here, considering denominator, # (x^2-9) # which becomes zero when #x=+-3# leads …

See explanation. Domain The domain is the largest subset of real numbers RR for which the function is defined. To find it we have to …

-3 Assume zero is in the middle of the numberline All numbers to the left of zero are negative All numbers to the right of zero are …

a=1, b=4, c=1 assuming that a,b,c in RR Assume that all terms of the equation to be real numbers. This problem has many sqrt …

1 So we know that on the real numbers, sin and cos are bounded. This means that -1<=cos (x)<=1 and -1<=sin (x)<=1 AA x in RR …
