How to calculate square root 1.4 without calculator

Mathematics
1 answer:
Oxana [17]3 years ago
6 0

Answer:

Approximate only

Step-by-step explanation:

the perfect square smaller than 1.4 is 1, because 1^2 =1

Take the difference between the two, 1.4 -1 = 0.4

Put the whole with 1. the part will be as follow:

1 \frac{0.4}{double~the ~whole} =1\frac{0.4}{2}

=1+0.2= 1.2

Note: just approximate!! with calculator, it is 1.18321
