The value of √0.0784 + √0.000784 is:
A{'text': '0.308'}
B{'text': '0.038'}
C{'text': '0.380'}
D{'text': '3.080'}
Answer & Solution
Correct answer: A. {'text': '0.308'}
1. √0.0784: 0.0784 = 784/10000, √784 = 28, √10000 = 100, so √0.0784 = 0.28.
2. √0.000784: 0.000784 = 784/1000000, √1000000 = 1000, so √0.000784 = 28/1000 = 0.028.
3. Sum: 0.28 + 0.028 = 0.308.
4. Hence the value is **0.308**.

A right triangle has hypotenuse 5 cm and one side 3 cm. The third side squared is:90 = 2 x 3 x 3 x 5. Since 2 and 5 are unpaired, 90 is:The square root of 6400 is:48 = 2x2x2x2x3 has one unpaired 3. The smallest number to multiply 48 by to get a perfect 256 = 2x2x2x2x2x2x2x2. Pairing the factors, its square root is:Subtracting 1, 3, 5, ... from 81 reaches 0 at the 9th step. So the square root of 81 is:A perfect square has two integral square roots; the root symbol denotes only the:Finding a number whose square is known is called finding the:
