Answer:
6²
Step-by-step explanation:
Use the rule of exponents ...
(a·b)^c = a^c·b^c
Your expression has a=3, b=2, c=2.
3²·2² = (3·2)² = 6²

If you want to get more sophisticated than that, logarithms can get involved.
y = 8
11y + 4y + 60 = 180
11y + 4y = 120
15y = 120
A snowflake falls 90 feet in 1 minute.
60 ÷ 4 = 15
6 x 15 = 90
20 is the answer I got
