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, â€¦
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.
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.
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.
you turn the decimal into a fraction then you turn the fraction into a whole number and add a percent sign
The imaginary number (i) is defined as the square root of -1. If you multiply i by i you get -1
A whole number can be divided by its non-multiples to result in fraction as well as decimal.
0.535 is a fractional number in decimal form and there is no sensible way to turn it into a whole number.
To turn a fraction into a decimal you divide the top number (numerator) by the bottom number (denominator). For example: 4/5 = 0.8
The answer depends on what you consider to be a "regular" number.
If you know how to turn a mixed number into a fraction and a fraction into a decimal do that then make it negative.
To turn any fraction into a decimal you divide the top number by the bottom number. For 1/3 divide 1 by 3
You put your feet up and chill! The number is already in decimal form!
Keep the whole-number-part exactly as it is, and re-write the decimal part as a fraction.
Radicals can be turned into decimals by finding their square root.
You have to turn the percentage into a decimal.
You cannot. A mixed number, by definition, has a fractional part. In converting to a decimal number, you cannot get rid of that fractional part and so you can never convert it to a decimal integer.
You do nothing! A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So, the number 13579, in decimal is 13579 - exactly as it was.
Turn it into an improper fraction. Then take the top number and divide it by the bottom for a decimal. Change that into a percent.
To convert at fraction into a decimal, divide the top number (numerator) by the bottom number (denominator). Example: To convert 4/5 into a decimal: 4 ÷ 5 = .8
Take the decimal and multiply by 10. Then put that new number over 100, then simplify.
The square root of a number is a number which, when multiplied by itself, yields that original number. *Special note: Recall that two positive numbers when multiplied together equal a positive number, and two negative numbers when multiplied together equal a positive number. Let's look at some examples and it will become clear. 4 x 4 = 16 and -4 x -4 = 16 therefore the square root of 16 is +4 or -4. 6 x 6 = 36 and -6 x -6 = 36 therefore the square root of 36 is +6 or -6. Simple and easy. The square root of a positive number is both a positive and a negative number. But the square root of a negative number presents another problem. We can't multiply two identical numbers together to get a negative number because of the *Special note. So how do we evaluate the square root of, say, -4? We can't do it "directly" so we have to do it this way: sq rt -4 = (sq rt 4) x (sq rt -1) Note that we "broke down" the -4 into 4 x -1 so we'd have "room to work" the problem. We can evaluate the sq rt of 4 and get +2 and -2, and we'll write the sq rt -1 as i. The italicised "i" is used to denote sq rt -1 and permit us to find the square root of a negative number, and that "i" is for "immaginary number" here. There is no real number that can be found which is the square root of a negative number. We can only "imagine" the square root of a negative number, and the "i" lets us at least write something so we can make calculations.
To get a percent into a decimal, divide by 100.
first turn the mixednumber into a decimal
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.
23 can't be turned into a decimal it is a whole number you could turn it into a decimal if it was 23 1/2 that would be 23.5 but 23 as a decimal is 23
