sqaure root of 39 simplified

Question

anonymous · Answer

$$\sqrt{39} =?$$

anonymous · Answer

Prime factorize it....

anonymous · Answer

39 = 3*13.....it can be further simplified......but u can find ita value

$$\sqrt{39}=6.24$$

anonymous · Answer

calculating a numeric value of a square root isn't usually what they mean by "simplify".

anonymous · Answer

the hyptenuse of a right triangle is 8cm. If one leg of the triangle is 5cm. Find the other leg. Simplify your answer. <<< this is the question

anonymous · Answer

ok, great... 

a^2 + b^c = c^2
5^2 + b^2 = 8^2
25 + b^2 = 64
b^2 = 64 - 25 = 39
b = sqrt(39)

That's all you can do... there's no way to simplify sqrt(39).  If they want you to have a numerical answer, you can use a calculator, but typically, you just leave it as sqrt(39)

i meant hypotenuse

anonymous · Answer

usually, "simplify" a sqrt means something like "simplify sqrt(50)"

and you are supposed to realize that the stuff under the square root includes a factor that is a perfect square, like in this case, 50 = (25)(2)

So to simplify sqrt(50), you get sqrt(25 x 2) = 5sqrt(2)
