Answer:

4. x = 7

5. A

Step-by-step explanation:

you can't use a calculator ?

x² = 49

x = 7

sqrt(4) = 2

triple root (8) = 2

sqrt(16) = 4

only sqrt(2) is a never-ending sequence of digits without any repeating pattern after the decimal point. and that is the meaning of irrational numbers. they can never be described by an expression a/b, where a and b are integer numbers.
