How many PERFECT SQUARES lie strictly between 100 and 200?
A3
B4
C5
DInfinitely many
Answer & Solution
Correct answer: B. 4
The perfect squares strictly between 100 and 200 are 121 (=11²), 144 (=12²), 169 (=13²) and 196 (=14²). That's 4 perfect squares. The next one, 225 = 15², lies outside the range.

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:
