What is the square root of 16x^ 36?

Vsevolod [243]

Note that $\sqrt[2]{x}=x^{\frac{1}{2}}$

$\sqrt[2]{16x^{36}}=\sqrt[2]{4^2x^{18\cdot2}}$

$4^{2\cdot\frac{1}{2}}x^{18\cdot2\cdot\frac{1}{2}}=4^{\frac{2}{2}}x^{\frac{18\cdot2}{2}}$

$\boxed{4x^{18}}$

Hope this helps.

What is the sum? (1/x+2)+(1/x+3)+(1/X^2+5+6)

PolarNik [594]

For this case we have the following expression:
(1 / x + 2) + (1 / x + 3) + (1 / X ^ 2 + 5 + 6)
Rewriting we have:
(1 / x + 2) + (1 / x + 3) + (1 / ((x + 2) * (x + 3)))
By doing common factor we have:
(1 / ((x + 2) * (x + 3))) * (x + 3 + x + 2 + 1)
Rewriting:
(1 / ((x + 2) * (x + 3))) * (2x + 6)
The sum is:
((2x + 6) / ((x + 2) * (x + 3)))
Answer:
((2x + 6) / ((x + 2) * (x + 3)))
