√1234= 35.13 (rounded off)
√132.32= 11.5 (rounded off)
Trial and error.
add a decimal no. to reach the exact no. to solve.
Remember that the product of the decimal number you multiplied to itself is just accurate. there is no exact no. if you are looking for the square root of a non-square no. , the answer is just accurate.
so i decided to add
35.13 x 35.13= 1234.1169
35.12 x 35.12= 1233.4144
so 35.13 is more accurate than 35.12 .
same as 11.5 .
the procedure is just the same.
