√1.96

4 answers

I recognize 196 as 14^2

so √1.96 = 1.4
Thank you, How did you see that as I am still learning how to do Sq,roots DFo I multiply 1.96 by itself?
no, you multiply 1.4 by itself to get 1.96

just like for √25 , ask yourself
"what must I multiply by itself to get 25" ?
clearly 5x5 = 25
so √25 = 5

or
just use your calculator if you don't recognize perfect squares, which are

1, 4, 9, 16, 25, 36, etc
Oh I see Thank you, that helps me understand what I did wrong. Thank you very much
