what does 3 square root 2 mean 2 x 3 2 2 2 3 3 6 Exponents are similar except now we re multiplying the number to itself instead of adding it 2 2 squared 2 x 2 2 2 4 3 2 squared 3 x 3 3 3 3 9 Taking the square root is figuring out what number multiplied by itself is equal to the number under the square root symbol So
Algebra Square Root Calculator Step 1 Enter the radical expression below for which you want to calculate the square root The square root calculator finds the square root of the given radical expression If a given number is a perfect square you It is easy to work out the square root of a perfect square but it is really hard to work out other square roots Example what is 10 Well 3 3 9 and 4 4 16 so we can guess the answer is between 3 and 4

Squared is often written as a little 2 like this This says 4 Squared equals 16 the little 2 means the number appears twice in multiplying so 4 4 16 Square Root A square root goes the other direction 3 squared is 9 so a square root of 9 is 3 It is like asking Here is the rule when a and b are not negative ab a b And here is how to use it Example simplify 12 12 is 4 times 3 12 4 3 Use the rule 4 3 4 3 And the square root of 4 is 2 4 3 2 3 So 12 is simpler as 2 3 Example simplify 45 Start with 45 45 is 9 times 5 9 5 Use the rule 9 5
Definition and Notation The square root of a number a denoted sqrt a is the number b such that b 2 a text and b ge 0 The square root symbol sqrt is also sometimes called a radical The number or expression underneath the top line of the square root symbol is called the radicand When you simplify a square root you need to ensure you have removed all perfect squares With 3 8 you still have a perfect square inside the radical 3 8 3 4 2 3 4 2 3 2 2 6 2

2 years ago No because if you divide a number by itself like 10 10 then you would get 1 but the square root of 9 is 3 and if you were dividing a number by itself then all the square roots would be 1 Square roots mean you multiply the same number twice to equal another number When 3 is multiplied by itself it gives 9 as the product This can be written as 3 3 or 3 2 Here the exponent is 2 and we call it a square Now when the exponent is 1 2 it refers to the square root of the number For example n n 1 2 where n is a positive integer Square Root Definition
For example to find the square root of 30 with a precision of three numbers after the decimal point Step 1 a 30 is between 25 and 36 which have roots of 5 and 6 respectively Let us start with b 5 5 Step 2 e a b 30 5 5 5 45 45 Since b is not equal to e 5 500 5 454 continue calculation Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor
