If √7 = 2.646, find without using calculator,<br>the value<br>of<br>√0.0007​
Varvara68 [4.7K]

Answer:

√0.0007​ = 0.02646

Step-by-step explanation:

We know that:

√7 = 2.646

We want to find the value of:

√0.0007

Also we know the relations:

\frac{\sqrt{x} }{\sqrt{y} } = \sqrt{\frac{x}{y} }

Then:

\sqrt{0.0007} = \sqrt{\frac{7}{10,000} }

We can rewrite this as:

\sqrt{\frac{7}{10,000} } = \frac{\sqrt{7} }{\sqrt{10,000} }  = \frac{2.646}{100} = 0.02646

Reciprocal just means flipped you can put any whole number over 1 if it helps to see that

5/1 = 5

Since reciprocal is asking you to flip 5/1 meaning numerator becomes denominator and vice versa you end up with 1/5 being the reciprocal of 5
