Simple algebra is a branch of mathematics that deals with the manipulation and solving of equations using letters and symbols to represent unknown quantities.
To solve an equation, you need to isolate the variable on one side of the equation by using inverse operations. This means that if the variable is being multiplied, you need to divide to isolate it. If the variable is being added, you need to subtract. Once the variable is isolated, you can solve for its value.
A square root is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because 3 multiplied by itself is 9.
To find the square root of a number, you can use a calculator or use the long division method. For example, to find the square root of 25, you can divide 25 by 2, which is 12.5. Then, you can divide 25 by 12.5, which is 2. Repeat this process until you get a decimal number that is close to the actual square root.
A square root is the inverse operation of squaring a number, meaning it undoes the action of squaring. For example, the square root of 9 is 3 because 3 squared is 9. An exponent, on the other hand, is a number that indicates how many times a base number should be multiplied by itself. For example, 3 to the power of 2, written as 3^2, is 9.
