How do you simplify the square root of 63?
Sqrt (63)sqrt (9 * 7)sqrt (9) * sqrt (7)3 sqrt(7)
Are square root numbers rational?
In general, not usually.The square root of an irrational number is always irrational.The square root of a rational number is usually irrational, but not always. You can tell by this test:If both the numerator and denominator of the number expressed as a simplified fraction are perfect square numbers (a number whose square root is a whole number), then the square root of the whole fraction will be rational.Example: Sqrt(4) =2 (the positive one). Sqrt(1) = 1. Both are perfect squares.So sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2. Another one: sqrt(4/9) = 2/3.
Square root of 9x7?
Two ways to look at it: 1). sqrt( 9 x 7 ) = sqrt( 63 ) = 7.93725 (rounded) 2). sqrt( 9 x 7 ) = sqrt( 9 ) x sqrt( 7 ) = 3 x sqrt( 7 ) = 3 x 2.64575 (rounded) = 7.93725
How do you simplify the square root of 245?
sqrt(245) = sqrt(49*5) = sqrt(49)*sqrt(5) = 7*sqrt(5)
What is the geometric mean of 7 and 12?
Sqrt (7*12)sqrt (84)9.165
What is the geometric mean of 5 and 10 to the nearest whole number?
GM(5, 10) = sqrt(5*10) = sqrt(50) = 7.1 approx So, to the nearest whole number, the answer is 7.
A number whose positive square root is whole is a whole number?
Examples of such numbers are 49, where sqrt(49) = 7, 81, where sqrt(81) = 9. Such numbers are called square numbers.
How is the square root of -7 classified?
The square root of 7 is an irrational number. This means that there are no integer numbers a and b so that a/b=sqrt(7)
One eighth of the square root of 7 less than a number is 2 What is the number?
(sqrt(x-7))/8=2 (sqrt(x-7))/8=2 (sqrt(x-7))/8=2
When using a calculator to find the square root of a number what is the correct sequnce of steps?
Depending on the calculator, it can be : sqrt(number) = answer, or number, press sqrt, answer. examples : sqrt(49) press enter = 7 or put 49, press sqrt, answer is shown as 7.
Is 7 a whole number for 54?
No. 7 is a whole number and 54 is a whole number but 7 is not "a whole number for" any number.
What is the smallest number which 42000 must be multiplied for the result to be a square number?
Let's call this number b 42000 = 24 x 3 x 53 x 7 We have 42000 x b = a2 and a is an integer Then a = sqrt(42000 x b) = sqrt(b) x sqrt(24 x 3 x 53 x 7) sqrt(24 x 3 x 53 x 7) = 22 x sqrt(3) x 5 x sqrt(5) x sqrt(7) For a to be an integer sqrt(b) must be sqrt(3) x sqrt(5) x sqrt(7) at least Thus b = 105
What is the whole number boundaries of square root 117?
-11 < sqrt(117) < -10 and 10 < sqrt(117) < 11
What does radical twenty eight plus radical sixty three equal?
sqrt(28) + sqrt(63) =sqrt(7 x 4) + sqrt(7 x 9) =[ sqrt(7) x sqrt(4) ] + [ sqrt(7) x sqrt(9) ] =2 sqrt(7) + 3 sqrt(7) =5 sqrt(7) = 13.229 (rounded)
What is the sqrt of 28 divided by the sqrt 7?
4
What is the square root of 39 to the nearest whole?
sqrt(39) = ±6, to the nearest whole number.
What is the complex number of 7 plus square root of -121?
7 + sqrt(-121) => 7 + sqrt( -1 X 121) => 7 + sqrt(-1) X sqrt(121) => 7 + sqrt(-1) *+/-11 = > 7 +/= 11sqrt(-1) The sqrt(-1) is designated the letter 'i' ( small /lower case 'i'). Hence 7 +/- 11i NB If you can find the 'square root of '-1'' , then the mathemtical world. would like to hear from you.
