# How do you simplify -sqrt(1.96)?

Jul 17, 2016

$- \sqrt{1.96} = - 1.4$

#### Explanation:

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?

$- \sqrt{1. \left(\textcolor{m a \ge n t a}{96}\right)} \Rightarrow$ there will be ONE decimal place.

$- \sqrt{1.96} = - 1.4$
