Question

What is the inequality

Answer 1

Underroot of x = 12

x can be Option A because underroot of 125 is more than 12.
x cannot be option b because the under root of 144 is 12 and this wont be an inequality.
x cannot be Option C or D as the under root will be smaller 
X is Option E because the under root will be more
X is not F as the under root of 143 is less
Option A and E
