a and b are positive constants. If a > b, then which of the following is true? It is not possible to tell anything about the relationship between a^-3 and b^-3. a^-3 = b^-3 a^-3 greaterthanorequalto b^-3 a^-3 > b^-3 a^-3 lessthanorequalto b^-3 a^-3 Less than b^-3

Solution

a and b are positive constants

with a > b

lets take an example lets say a = 3 and b = 2

so , a^-3 = 1/27 , b^-3 = 1/8

so we can say that a^-3 < b^-3

hence, last option is correct
