To determine which number is a perfect square, you need to find the square root of each option and check if the resulting number is a whole number.
Let's try this method for each option:
A. To find the square root of 45, we can use a calculator, which gives us approximately 6.7. Since 6.7 is not a whole number, 45 is not a perfect square.
B. To find the square root of 169, we take the square root of 169, which is 13. Since 13 is a whole number, 169 is a perfect square.
C. To find the square root of 48, we use a calculator, which gives us approximately 6.9. Since 6.9 is not a whole number, 48 is not a perfect square.
D. To find the square root of 110, we use a calculator, which gives us approximately 10.5. Since 10.5 is not a whole number, 110 is not a perfect square.
Therefore, the only number that is a perfect square among the given options is B. 169.
What is the square root of 48? Is it a whole number?
