To "square" means to calculate the value of a number multiplied by itself. A simple example is three squared, or three times three. Mathematically the problem looks like this: 32= 3 × 3 = 9. The exponent 2, written as superscript 2 (N2), says to multiply a number (N) by itself,...
To calculate feet squared (or sq. ft. for short), determine the length and width of the area you are working with, measured in feet. Multiply the length by the width and you’ll have the square feet. Here’s a basic formula you can follow: Length (in feet) x width (in feet) = ...
To find the square root of a number, we just see by squaring which number would give the actual number. It is very easy to find the square root of a number that is a perfect square. Perfect squares are those positive numbers that can be expressed as the product of a number by itself...
R squared (R2)is a regression error metric that justifies the performance of the model. It represents the value of how much the independent variables are able to describe the value for the response/target variable. Thus, an R-squared model describes how well the target variable is explained b...

The square root of any number is equal to a number, which when squared gives the original number. Let us say m is a positive integer, such that √(m.m) = √(m2) = m In mathematics, a square root function is defined as a one-to-one function that takes a positive number as an ...
When you multiply one measurement in meters by another measurement in meters, the result should always be labeled as square meters to avoid confusion. You can also write square meters as meters2or m2, which is read as meters squared.
