The answer
let A= 2^3 and B=3^2
the main formula is as following:
a^n = axaxax ....xa (n times), for all n upper than or equal 1
for example
a^3 = a x ax a
in our case
A= 2^3 = 2x2x2= 4x2 =8
B=3^2 = 3x 3= 9
so, Luther's evaluation was wrong, by contrast <span>Wade evaluated 32 as 9 correctly

Answer:
The sound in a loud part of the room is 10000 times louder than sound in a quiet part of the same place.
Step-by-step explanation:
The acoustic intensity sound is a logarithmic function whose form is:
Where:
- Acoustic intensity sound, measured in decibels.
- Reference sound intensity, measured in watts per square meter.
- Real sound intensity, measured in watts per square meter.
Sound intensity is now cleared:
The ratio of the sound intensity in a loud part to the sound intensity in a quiet part is:
The sound in a loud part of the room is 10000 times louder than sound in a quiet part of the same place.
How to convert fraction to decimalFor example, in order to get a decimal fraction, 3/4 is expanded to 75/100 by multiplying the numerator by 25 and denominator by 25:<span><span>3=3×25=75=0.75</span><span>44×25100</span></span>. the answer is 4.6 for your question.
ΔABC is an isosceles triangle therefore ∡B = ∡C.
ΔDCA is a rectangular triangle therefore ∡y + ∡C = 90°
22° + ∡C = 90° |subtract 22° from both sides
∡C = 68°
