Q: What is the sq root of -9?

Write your answer...

sq. root of (80/125)= sq. root of [(9)(2)(5)/(25)(5)]= (sq. root of 9)(sq. root of 2)/sq. root of 25= (3/5)sq. root of 2

9

No. The sq root of 84 is 9.16555515139. 81 is a perfect square, where the sq root is 9.

Yes but only if the given numbers are +4 and +9

Square root of (1296) =Square root of (16 x 81)=SQ. root of (16) x Sq. root of (81) =4 x 9 =36

sq. root of 75 = sq. root of (25 x 3) = (sq. root of 25)(sq. root of 3) = 5(sq. root of 3)

Sq root of 81 = 9 because 9x9=81Sq root of 121 = 11 because 11x11=1219/11 is the answer.

(3 root 7) squared = (3 root 7) (3 root 7) = (3x 3) ( sq root 7 x 7) = 9 x sq root 49 = 9 x 7 = 63

11.18033989 is the sq. root of 125.

sq rt of 81 is 9 sq rt of 100 is 10 sq rt of 83 is between 9 and 10 and thus is not an integer/ counting number

sq root (112.7) = 10.6160256.... sq root (112.7) = 10.6160256....

( (sq. root ( 3 ) ) * ( 1 / 9 ) ) cubed

36 (sq rt 81 x sq rt 16 = 9 x 4 = 36)

4

It is the square root of 30

if you know the area, square root on your calculator. therefore sq(4)= 2 sq(9)=3

Sq root of 2 * sq root of 8 = 1.414 * 2.828 = 3.998792

Find the factors of 484484= (4)(121)Square root of (484) = Sq. root (4 x 121) = Sq. root (4) x sq. root of (121) = 2(11) = 22

Square root of 6 = 2.44948 Sq root of 6 + Sq root of 6 = 2.44948 + 2.44948 = 4.89896

3.5714

The square root of 4 * the square root of 81 four possible combinations:-2 * -9-2 * 92 * -92 * 9and two possible answers-2 * 9 and 2 * -9 = -18-2* -9 and 2 * 9 = 18

f(x)=x2f -1(x)=sq. root(x)__________________y2=x [invert y](y2)-1=x = 1/y2=xsq. root(1/y2)= sq. root (x) [y can't be squared, root both sides](1/y)=sq. root(x)y-1=sq. root(x)

If you are using integers, it is prime. x2 - 45 can be factored as the difference of squares IF you use irrational numbers (sq roots) Ex x2 - 16 = (x + 4)(x - 4) ..... notice 4 is sq root of 16 so you can sreate a rule... x2 - A = (x + sq root A)(x - sq root A) So ... AND THIS IS SOMETHING NO HIGH SCHOOL BOOK EVER TEACHES.... x2 - 45 = (x + sq root 45)(x - sq root 45) You should simplify the sq root 45 to be (3 times sq root 5) in both factors.

sq. root of 98 =sq. root of 49*2 =7*sq.root of 2 =7*1.414 =9.898

if there is no integer answer, they are irrationalex. sq root 5 is irrational but sq root 9 = 3 so it is rational,integer, counting numberif you are taking sq root of a negative they are imaginary ex. sqroot (-9)=========================The square roots of all positive real numbers are real numbers.The square roots of all negative real numbers are imaginary numbers.Some square roots are rational, but the vast majority are irrational.
