Can someone please answer this for me i cant figure it out.
Jlenok [28]
<h3>Answer:</h3>

\displaystyle x^{\frac{2}{3}}

<h3>Step-by-step explanation:</h3>

The rules of exponents tell you ...

... (a^b)(a^c) = a^(b+c) . . . . . . applies inside parentheses

... (a^b)^c = a^(b·c) . . . . . . . . applies to the overall expression

The Order of Operations tells you to evaluate inside parentheses first. Doing that, you have ...

... x^(4/3)·x^(2/3) = x^((4+2)/3) = x^2

Now, you have ...

... (x^2)^(1/3)

and the rule of exponents tells you to multiply the exponents.

... = x^(2·1/3) = x^(2/3)

-5mn + 6n - 4m + 2mn + 8n + 3m simplify please show your work
BARSIC [14]

Answer:

-3mn + 14n - m is your answer.

Step-by-step explanation:

Combine like terms (terms with the same amount of variables). Reorder so that it is so:

(-5mn + 2mn) + (6n + 8n) + (-4m + 3m)

Combine like terms. Add or subtract the variables. Note that if there is no number, it is assumed that there is a 1:

(-5mn + 2mn) = (2mn - 5mn) = -3mn

(6n + 8n) = 14n

(-4m + 3m) = 3m - 4m = -m

(-3mn) + (14n) + (-m)

-3mn + 14n - m is your answer.
