The frequency of A4 is 440.00 Hz. what is the frequency of A6, which is two octaves above A4?

2 answers:

5 0

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above: <span>The frequency of A4 is 440.00 Hz.

2. So, you must apply the following formula to calculate the frequency of A6, which is two octaves above:

(2</span>^n)f

Where n is the octaves above and f is the known frequency.

3. Therefore, you have:

A6=(2^n)f
A6=(2^2)(440.00 Hz)
A6=1760 Hz

Therefore, the answer is: A6=1760 Hz.

The formula for getting the unknown frequecy is given by, (2∧n)×f.
Where n ⇒the number of octavos above A4 and
f ⇒the given frequency

So, the frequency of A6 is calculated as follows.

Frequency = (2∧2)×440.00
= 1760.00 Hz

Step-by-step explanation:

Since the denominator of each of those rational exponents is a 4, that means that the radical is a 4th root. The numerator of each exponent serves as the power on the given base. For example,

$2^{\frac{3}{5}}$ can be rewritten as

$\sqrt[5]{2^3}$

The little number that sits outside the radical, resting in the bend, is called the index. Our index is 4 (same as saying the 4th root). Put everything under the 4th root and let the numerator be the powers on each base:

$\sqrt[4]{6^1*b^3*c^1}$ which is written simpler as:
