Which expression is equivalent to 128x^5y^6 \ 2x^7y^5 ? Assume x > 0 and y > 0.
N76 [4]

Answer: Last option.

Step-by-step explanation:

Given the expression:

\sqrt{\frac{128x^5y^6}{2x^7y^5}

The Quotient of powers property states that:

\frac{a^m}{a^n}=a^{(m-n)}

And the Power of a powet property states that:

(a^m)^n=a^{mn}

Then, applying these properties, you get:

=\sqrt{\frac{(2^3)^26y}{x^2}

Now you must remember that:

\sqrt[a]{a^n}=a

Therefore, simpliying the expression, you get:

=\frac{2^3\sqrt{y}}{x}=\frac{8\sqrt{y}}{x}

Flura [38]
It took them 4 days until they arrived at their destination.

314 × 4 = 1256

Another way of solving it:

Total amount of miles ÷ miles per day = The amount of days.

1256 ÷ 314 = 4
