The square root of 164 to the nearest integer is 13.
My question:
How do I find the answer to such questions without using a calculator?
wow nice trick you presented engineer. I wonder people figure these kind of things out....
I remember learning that technique in my seventh grade math class. Of course calculators were not ubiquitous then. I guess no one teaches paper and pencil techniques any more.
They don't even teach trig and logarithm tables.
It's all a key on a calculator.
