Answer:

The square root is 1.90

Explanation:

Given

x = √(3.6)

Required

Find x

Express 3.6 as 36/10

So, we have:

x = (√(36))/(√(10))

This gives

x = (6)/(√(10))

Rationalize

x = (6)/(√(10))*(√(10))/(√(10))

x = (6√(10))/(10)

Using a calculator

$√(10) \approx 3.16$

So, we have:

x = (6*3.16)/(10)

x = (18.96)/(10)

x = 1.896

Approximate

x = 1.90
