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 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.
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.
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.
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
To turn any fraction into a decimal you divide the top number by the bottom number. For 1/3 divide 1 by 3
The answer depends on what you consider to be a "regular" number.
