Final answer:
To estimate the square root of 75 to the nearest whole number, we find the perfect squares closest to 75. Since 75 is closer to 81 than to 64, the estimate is 9.
Step-by-step explanation:
To estimate the square root of 75 to the nearest whole number, we need to find the perfect squares that are closest to 75.
The perfect squares less than 75 are 64 (8^2) and 81 (9^2). On the number line, 75 is closer to 81 than to 64. So, the square root of 75 is close to 9. Therefore, the estimate of the square root of 75 to the nearest whole number is 9.
