Question

Solve it as fast as possible
Under root 175-1/4

Answer 1

under root 175- 1/4

under root (700- 1)/4

under root 699/4

under root 699/ under root 4

under root 699/2

or

you can write it as

26.4/2

= 13.2 ( this amswer is just an approximation)

correct answer is

under root 699/2

i solved this by first subtracting 1/4 from 175 and than taking the under root of the answer obtained by subtracting these two.
