#-sqrt1.96 = -1.4#

It is very useful to know the squares of the numbers up to 20 by heart.

#14^2 = 196#

In this case, it is obvious that we are working with a root of 14, but is it 14, 1.4 or 0.14?

When working with square roots of decimals, pair the decimals from the decimal point. For each pair there must be a decimal place.

IN this case, it is obvious that we are working with a root of 14,
but is it 14, 1.4 or 0.14?

#-sqrt[1.(color(magenta)(96)) ] rArr# there will be ONE decimal place.

#-sqrt1.96 = -1.4#
