Answer:
1) Irrational.
2) Irrational.
Step-by-step explanation:
We have been given two numbers. We are asked to determine whether the given numbers are rational or irrational.
We know that a number is a known as rational number, when we can represent it as a fraction or it has terminating decimals.
A number is a known as rational number, when it has non-repeating and non-terminating decimals.
1). 
Since our given number has non-repeating or non-terminating decimal, therefore, given number is an irrational number.
2) 
Since our given number has non-repeating or non-terminating decimal, therefore, given number is an irrational number.
X² = 5
take root to both side to clear the square
√x² = ±√5
X = ±√5

Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
X = k*y^2 * z
100 = 6^2*5*k,
k=0.555
x=0.555zy^2
x=o.555(8^2)(2)=71.1112.
Hope that helps!
