# Is there a calculator that will simplify square roots from a decimal to a square root?

Apr 20, 2015

I believe any scientific calculator can do this. Just press the sqrt key and enter the decimal number, then press = and you should get the square root as a decimal number.

For example, if you want to find the square root of 15.087, you would press the sqrt key and enter 15.087, press = and you get
3.884198759075. You would probably round to 3.8842 due to significant figures.

It's not really clear what you want to do.
It sounds to me like you want to be given a decimal and write is as a square root.

If that is your question, then simply square the decimal and round. (If it's not too far away.)

Example 1
${0.866}^{2} = 74.9956 \approx 75$, so

$0.866 \approx \sqrt{75}$

Example 2

${1.527}^{2} = 2.331729 \approx 2 \frac{1}{2} = \frac{7}{3}$

So: $1.527 \approx \sqrt{\frac{7}{3}}$
