Here are the estimated square roots of 108 and the steps to get them:
√108 ≈ √100 = 10 (Note that 108 is between 100 and 121)
√108 ≈ √121 = 11 (Note that 108 is closer to 121 than to 100)
Therefore, we can estimate √108 to the nearest tenth as 10.4
So, the estimated square root of 108 to the nearest tenth is 10.4.
