Answer:

A. 4xy $\sqrt[4]{3y}$

Step-by-step explanation:

4√768x⁸y⁵

---> factor 768 --> 4x4x4x4x3

---> x⁸ = x⁴⁺⁴ = x⁴ . x⁴

---> y⁵ = y⁴⁺¹ = y⁴ . y¹

4√4⁴x3 x⁴ . x⁴ . y⁴ .y

since is 4th root, all the numbers with power to 4 comes out of the root

4x.x.y $\sqrt[4]{3y}$

4x²y $\sqrt[4]{3y}$

(a) What resonant frequency would you expect from blowing across the top of an empty soda bottle that is 24 cm deep, if you assu

Kryger [21]

Answer:

a) 357.29 Hz

b) 535.9375 Hz

Step-by-step explanation:

v = Velocity of sound in air = 343 m/s

l = length = 24 cm

$l=\frac{1}{4}\lambda \\\Rightarrow \lambda=4l$

$f=\frac{v}{\lambda}\\\Rightarrow f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.24}\\\Rightarrow f=357.29\ Hz$

∴ Resonant frequency is 357.29 Hz

b) Here one third is filled with soda

So, length becomes $l=24-\frac{24}{3}=16\ cm$

$f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.16}\\\Rightarrow f=535.9375\ Hz$

∴ Resonant frequency is 535.9375 Hz

Rewrite the expression. Use and exponent, rather than repeated multiplication (-4)(-4)

IrinaK [193]

-4²

Any number repeatedly multiplied by itself has an exponent. so (-4)(-4) has an exponent of 2 while (-4)(-4)(-4) would have an exponent of 3 and be written as -4³.

Also extra tip: Negative numbers multiplied by a negative number will always be positive.
