We have been given an expression \frac{2^5}{6^5}. We are asked to choose the expressions, which are equivalent to our given expression.

Using exponent property \frac{1}{a^n}=a^{-n}, we can rewrite our given expression as:

\frac{2^5}{6^5}=2^5\cdot 6^{-5}

Upon looking at our given choices, we can see that option D is the correct choice.

Let us simplify our given expression.

\frac{2^5}{6^5}=\frac{2^5}{(2\cdot 3)^5}

\frac{2^5}{6^5}=\frac{2^5}{2^5\cdot 3^5}

Upon cancelling out 2^5 from numerator and denominator, we will get:

\frac{2^5}{6^5}=\frac{1}{3^5}

Using exponent property \frac{1}{a^n}=a^{-n}, we will get:

\frac{1}{3^5}=3^{-5}

Therefore, option B is a correct choice as well.

The figure shows a large triangle divided into two smaller triangles what is the value of x in the figure
nata0808 [166]

Answer:

40

Step-by-step explanation:

Find the other missing angle, which is supplementary to 100 first.

Supplementary angels are a sum of 180

The missing angle is 180-100 = 80

Now use that to find missing angle x

All angles in the triangle have a sum of 180

180 = 60+80+x

180-60-80=x

40 = x
