Square root of 3.24 =
kvv77 [185]

Question says to find the square root of 3.24.

To find square root of decimal numbers, we can start by converting them into fraction so that decimal gets removed then find square root of numerator and denominator separately.

there are two digits after decimal in 3.24 so we can rewrite 3.24 as 324/100

Now let's find square root of the resulting fraction

\sqrt{3.24}=\sqrt{\frac{324}{100}}= \frac{\sqrt{324}}{\sqrt{100}} = \frac{18}{10} = 1.8

Hence final answer is 1.8.

DaniilM [7]

Answer:

The answer is "\bold{(7.1-8.3) \pm 1.665 \sqrt{\frac{(1.7)^2}{50}+\frac{(1.9)^2}{39}} }\\\\"

Step-by-step explanation:

Given values:

\bar{x_1}=7.1\\\\\bar{x_2}=8.3\\\\s_1=1.7\\\\s_2=1.9\\\\n_1=50\\\\n_2=39

Using formula:

\to (\bar{x_1} -\bar{x_2}) \pm t \sqrt{\frac{(s_1)^2}{n_1}+\frac{(s_1)^2}{n_2}} \\\\

Put the values in the above formula:

\to (7.1-8.3) \pm 1.665 \sqrt{\frac{(1.7)^2}{50}+\frac{(1.9)^2}{39}} \\\\
