Is a square root commutative?
Yes, it is. sqrt(a+b)=sqrt(b+a) sqrt(a) times sqrt(b) = sqrt(b) times sqrt(a)
Square root 12 over b square?
Assuming the equation is sqrt (12/b2), the solution is: sqrt 12 / sqrt b2 = sqrt (4*3) / b = 2 sqrt 3 / b
What is the Geometric mean of 32 and 50?
Geometric Mean of A and B is the square root of A times B, in this case sqrt 1600 which is 40
How do you divide surds?
Okay, this is the rule for dividing surds: sqrt (a) ______ sqrt (b) = sqrt (a/b) so for example you had sqrt 3 _____ sqrt 21 = sqrt (3/21) = sqrt (7) more complicated... 3 sqrt(3) ________ 4 sqrt(21) = 3/4 sqrt (3/21) = 3/4 sqrt (7) It's pretty easy as long as you can remember the rule. I hope that helps. XD
Give one example for if you add two irrational number and answer should get in rational number?
Suppose A = 2 + sqrt(3) and B = 5 - sqrt(3) Then A and B are two irrational numbers but A + B = 2 + sqrt(3) + 5 - sqrt(3) = 7 which is rational.
