What is the square root of 16x^<br> 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.

Expand and simplify (2x+5y) (x-3y)
Dmitry [639]
Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
2x^2-3xy
for the first one.

2nd one:
5y(x-3y)
you'd get:
+5xy-3y^2

Put them both together:
2x^2-3xy+5xy-3y^2

Combine like terms.

Your Answer:
2x^2+2xy-3y^2
