Which among `4^(-2),3^(-2),2^(-2)` and `5^(-2)` is the greatest?A. `4^(-2)`B. `3^(-2)`C. `2^(-2)`D. `5^(-2)` |
|
Answer» Correct Answer - C `4^(-2),3^(-2),5^(-2)` `rArr (1)/(4^2),(1)/(3^2),(1)/(2^2),(1)/(5^2)` `rArr (1)/(16),(1)/(9),(1)/(4),(1)/(25)` Since , the numerators of the given fractions are same, the fraction which has the least denominator has the greatest value. `therefore (1)/(4)` is the greatest among the given fractions. Hence, the correct option is (c). |
