Answer:
frequency= 165Hz
period= 
Step-by-step explanation:
1. To calculate the frequency using the formula:
f = v/λ
where,
f=frequency (what the question asked)
v=speed of wave (given in the question=330m/s)
λ=wavelength (given in the question=2m)
SO,
= 165Hz
2. To calculate the period use the formula:
since 
therefore, 
where,
f= frequency (what we solved above=165Hz)
T= period (what the question asked)
SO,
The answers are...
B. (3 ^3) ^9 * (7 ^3) ^6
D. (3 ^3 + 3 ^9) * (7 ^6 + 7 ^3)

Answer:
Step-by-step explanation:
