Question

Write true/false
a. A number having 3 zeros at the end is perfect square
b. Multiplicative inverse of any number is its reciprocal
c. Composite numbers cannot be divided by other numbers
d. Additive inverse of any number is its reciprocal
e. Rational numbers cannot be written ​

Answer 1

Answer:

a)False

b)True

c)False

d)False

e)False

Step-by-step explanation:

a) False because there are even number of zeros in the end of perfect square.

b) True, Multiplicative inverse of any number is its reciprocal. Ex- Reciprocal of 2/3 = 3/2 & Multiplicative inverse of 2/3 = 3/2  . You can see that both the values are same. Therefore, it is True.

c) False, composite numbers can be divided by other numbers.

d) False, additive inverse of any number is not it reciprocal. Only the sign changes. Ex. Additive inverse of 5 = -5 & Reciprocal of 5 = 1/5  . Since both the values are different. Therefore, the statement is True.

e) False, Rational numbers can be written.
