162
≈ 12.73/1
≈ 1273/100
≈ 12 73/100



What is the square root of 162 written with an exponent?
All square roots can be converted to a number (base) with a fractional exponent. The square root of 162 is no exception. Here is the rule and the answer to "the square root of 162 converted to a base with an exponent?":

b = b½

162 = 162½



How to find the square root of 162 by long division method
Here we will show you how to calculate the square root of 162 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 162 by hand before modern technology was invented.

Step 1)
Set up 162 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:

16200



Step 2)
Starting with the first set: the largest perfect square less than or equal to 1 is 1, and the square root of 1 is 1. Therefore, put 1 on top and 1 at the bottom like this:

1
16200
1



Step 3)
Calculate 1 minus 1 and put the difference below. Then move down the next set of numbers.

1
16200
1
062



Step 4)
Double the number in green on top: 1 × 2 = 2. Then, use 2 and the bottom number to make this problem:

2? × ? ≤ 62

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 2. Replace the question marks in the problem with 2 to get:

22 × 2 = 44.

Now, enter 2 on top, and 44 at the bottom:

12
16200
1
062
044



Step 5)
Calculate 62 minus 44 and put the difference below. Then move down the next set of numbers.

12
16200
1
062
044
01800



Step 6)
Double the number in green on top: 12 × 2 = 24. Then, use 24 and the bottom number to make this problem:

24? × ? ≤ 1800

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 7. Now, enter 7 on top:

127
16200
1
062
044
01800

That's it! The answer is on top. The square root of 162 with one digit decimal accuracy is 12.7. Did you notice that the last two steps repeat the previous two steps. You can add decimals by simply adding more sets of 00 and repeating the last two steps over and over.
