Question

square root of 1 plus x by 144 equal to 13 by 2

Answer 1

rt(1 +x/144) = 13/12
Squaring both sides:
1 + x/144 = 169/144
x/144 = 169/144 - 1
x/144 = 169-144/144
x/144 = 25/144
x = 25
Hope it helps.

Answer 2

Hey,
√1+x/144=13/12
Transferring square root to the right hand side,
1+x/144=(13/12)^2
1+x/144=169/144
144+x/144=169/144
Now, 144 is cancelled on both the sides,
144+x=169
x=25.
Hope this helps you buddy!!
