Find the square root of 3.6 upto 2 decimal places. *With Solution I need*
almond37 [142]

Answer:

The square root is 1.90

Step-by-step explanation:

Given

x = \sqrt{3.6}

Required

Find x

Express 3.6 as 36/10

So, we have:

x = \frac{\sqrt{36}}{\sqrt{10}}

This gives

x = \frac{6}{\sqrt{10}}

Rationalize

x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}

x = \frac{6\sqrt{10}}{10}

Using a calculator

\sqrt{10} \approx 3.16

So, we have:

x = \frac{6*3.16}{10}

x = \frac{18.96}{10}

x = 1.896

Approximate

x = 1.90

nikitadnepr [17]

Answer:

-9

Step-by-step explanation:

( \sqrt[4]{7}  + 2)( \sqrt[4]{7}  - 2)( \sqrt{7}  + 4) \\  = ( { \sqrt[4]{7} }^{2}  - {{2} }^{2} )( \sqrt{7}  + 4) [because (a+b)(a-b) = a² - b²]\\  = ( \sqrt{7}  - 4)( \sqrt{7}  + 4) \\  =   { \sqrt{7} }^{2}  -  {4}^{2}[because (a+b)(a-b) = a² - b²]  \\  = 7 - 16 \\  =  - 9
