The value of √(248 + √(52 + √144)) is:
A{'text': '16'}
B{'text': '12'}
C{'text': '14'}
D{'text': '18'}
Answer & Solution
Correct answer: A. {'text': '16'}
1. Work outward from the innermost radical.
2. √144 = 12.
3. Next: √(52 + 12) = √64 = 8.
4. Finally: √(248 + 8) = √256 = 16.
5. Hence the value is **16**.

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:
