To find the radicant for each decimal, we need to square the number. The radicand is the number inside the square root symbol. So, if $x = \sqrt{y}$, then $y = x^2$.
Here are the step-by-step calculations for each problem:
Left Column:
1.
$1.8$:
$1.8 \times 1.8 = 3.24$
So, $1.8 = \sqrt{3.24}$
2.
$0.2$:
$0.2 \times 0.2 = 0.04$
So, $0.2 = \sqrt{0.04}$
3.
$2.5$:
$2.5 \times 2.5 = 6.25$
So, $2.5 = \sqrt{6.25}$
4.
$0.3$:
$0.3 \times 0.3 = 0.09$
So, $0.3 = \sqrt{0.09}$
5.
$0.6$:
$0.6 \times 0.6 = 0.36$
So, $0.6 = \sqrt{0.36}$
6.
$1.4$:
$1.4 \times 1.4 = 1.96$
So, $1.4 = \sqrt{1.96}$
7.
$1.5$:
$1.5 \times 1.5 = 2.25$
So, $1.5 = \sqrt{2.25}$
8.
$0.7$:
$0.7 \times 0.7 = 0.49$
So, $0.7 = \sqrt{0.49}$
9.
$0.5$:
$0.5 \times 0.5 = 0.25$
So, $0.5 = \sqrt{0.25}$
10.
$0.1$:
$0.1 \times 0.1 = 0.01$
So, $0.1 = \sqrt{0.01}$
Right Column:
11.
$0.4$:
$0.4 \times 0.4 = 0.16$
So, $0.4 = \sqrt{0.16}$
12.
$1.3$:
$1.3 \times 1.3 = 1.69$
So, $1.3 = \sqrt{1.69}$
13.
$1.7$:
$1.7 \times 1.7 = 2.89$
So, $1.7 = \sqrt{2.89}$
14.
$0.8$:
$0.8 \times 0.8 = 0.64$
So, $0.8 = \sqrt{0.64}$
15.
$1.2$:
$1.2 \times 1.2 = 1.44$
So, $1.2 = \sqrt{1.44}$
16.
$1.9$:
$1.9 \times 1.9 = 3.61$
So, $1.9 = \sqrt{3.61}$
17.
$1.1$:
$1.1 \times 1.1 = 1.21$
So, $1.1 = \sqrt{1.21}$
18.
$0.9$:
$0.9 \times 0.9 = 0.81$
So, $0.9 = \sqrt{0.81}$
19.
$1.6$:
$1.6 \times 1.6 = 2.56$
So, $1.6 = \sqrt{2.56}$
20.
$2.1$:
$2.1 \times 2.1 = 4.41$
So, $2.1 = \sqrt{4.41}$
Final Answer:
Left Column:
$1.8 = \sqrt{3.24}$
$0.2 = \sqrt{0.04}$
$2.5 = \sqrt{6.25}$

$0.6 = \sqrt{0.36}$
$1.4 = \sqrt{1.96}$
$1.5 = \sqrt{2.25}$
$0.7 = \sqrt{0.49}$
$0.5 = \sqrt{0.25}$
$0.1 = \sqrt{0.01}$
Right Column:
$0.4 = \sqrt{0.16}$
