Represent the number 108 in expanded form and exponent
lubasha [3.4K]

<h3>108 = 3³ × 2²</h3>

<h3>Further explanation</h3>

Let's recall following formula about Exponents and Surds:

\boxed { \sqrt { x } = x ^ { \frac{1}{2} } }

\boxed { (a ^ b) ^ c = a ^ { b . c } }

\boxed {a ^ b \div a ^ c = a ^ { b - c } }

\boxed {\log a + \log b = \log (a \times b) }

\boxed {\log a - \log b = \log (a \div b) }

<em>Let us tackle the problem!</em>

\texttt{ }

108 = 54 \times 2

108 = (27 \times 2) \times 2

108 = (9 \times 3) \times 2 \times 2

108 = (3 \times 3) \times 3 \times 2 \times 2

108 = 3^3 \times 2^2

\texttt{ }

<h3>Conclusion:</h3>

The number 108 could be represented in expanded form and exponent as following:

\boxed{ 108 = 3^3 \times 2^2 }

What is length of the altitude of the equilateral triangle below?
Lina20 [59]

Answer: OPTION D.

Step-by-step explanation:

Given the equilateral triangle shown in the figure, you need to find the value of the altitude "a".

In order to find the altitude, you can use the following Trigonometric Identity:

tan\alpha =\frac{opposite}{adjacent}

In this case you can identify that:

\alpha=60\°\\\\opposite=a\\\\adjacent=2\sqrt{3}

Therefore, you can substitute values into tan\alpha =\frac{opposite}{adjacent}:

tan(60\°)=\frac{a}{2\sqrt{3}}

Finally, you must solve for the altitude "a". Then, this is:

 (tan(60\°))(2\sqrt{3})=a\\\\a=6

Notice that this result matches with the value shown in Option D.
