Best option is to use a calculator.
Failing that, use the Newton-Raphson method which entails making a guess at the answer and then improving on it. Repeating the procedure should lead to a better estimate at each stage.
To start with, if you want to find the square root of 405, define f(x) = x2 - 405.
Then finding the square root of 405 is equivalent to solving f(x) = 0.
Let f'(x) = 2x. This is the derivative of f(x) but you do not need to know that to use the N-R method.
Start with x0 as the first guess.
Then let xn+1 = xn - f(xn)/f'(xn) for n = 0, 1, 2, …
After a few iterations, xn will be very close to the required square root.
If you start with 20, whose square is 400, the second iteration gives a result that is accurate to 8 decimal places.
Radicals can be turned into decimals by finding their square root.
No. The square root of 9999 is 3 sqrt(1111), which is not an integer, which in turn means that 9999 is not a square number.
In most cases you cannot since the square root is an irrational number, unlike a fraction which is rational.
The imaginary number (i) is defined as the square root of -1. If you multiply i by i you get -1
You turn a fraction into a decimal by dividing the top number by the bottom. And you turn a decimal into a percent by multiplying the decimal by 100.
Go 3.75 units of distance in any direction. Turn 90 degrees clockwise and go 3.75 units of distance in a straight line. Turn 90 degrees clockwise and go 3.75 units of distance in a straight line. Turn 90 degrees clockwise and go 3.75 units of distance in a straight line.You will have travelled along a square route whose total distance is 15 units. Alternatively you could have turned counter clockwise each time.
Go 7 units of distance in any direction. Turn 90 degrees clockwise and go 7 units of distance in a straight line. Turn 90 degrees clockwise and go 7 units of distance in a straight line. Turn 90 degrees clockwise and go 7 units of distance in a straight line.You will have travelled along a square route whose total distance is 28 units. Alternatively you could have turned counter clockwise each time.
you turn the decimal into a fraction then you turn the fraction into a whole number and add a percent sign
Go 1.75 units of distance in any direction. Turn 90 degrees clockwise and go 1.75 units of distance in a straight line. Turn 90 degrees clockwise and go 1.75 units of distance in a straight line. Turn 90 degrees clockwise and go 1.75 units of distance in a straight line.You will have travelled along a square route whose total distance is 7 units. Alternatively you could have turned counter clockwise each time.
To turn any fraction into a decimal you divide the top number by the bottom number. For 1/3 divide 1 by 3
The square root of b is a number that, when multiplied by itself (i.e- when it is squared), results in b; if ais the square root of b, then b = a2.Most numbers do not have a square root because no number multiplied by itself will provide the correct result. Numbers that do have a square root are called Square Numbers.Some examples of square numbers:1 * 1 = 12 * 2 = 43 * 3 = 94 * 4 = 165 * 5 = 256 * 6 = 36
The answer depends on what you consider to be a "regular" number.
