Answer:

Step-by-step explanation:

The square root of a positive number cannot be negative.   False.  There are two square roots, one positive and one negative.

All positive numbers have two square roots.   True.  See above.

0 18 = 9 because 9(2) = 18.     Unable to answer; "0 81" is invalid.  Note that

√81 = ±9

49 = 7 because 7(7) = 49.  Invalid statement.  49 never equals 7.  Perhaps you meant √49 = ±7

25 = 5 because 52= 25.  Invalid statement.  Perhaps you meant √25 = ±5.

Please, before you do any more square root problems, learn how to type the  " √ " symbol or equivalent, such as "sqrt( "
