Simplify 81^5=3^w and find w

Mathematics
1 answer:
Allisa [31]3 years ago
8 0

Answer:

w = 20

Step-by-step explanation:

<u>Step 1:  Find common bases</u>

81^5 = 3^w

81 → 3 * 3 * 3 * 3 → 3^4

Therefore, 81 = 3^4

81^5 → 3^(^4^)^*^5 → 3^2^0

So... 3^2^0 = 3^w

Since same base now, we can evaluate the exponents by themselves.

20 = w

Answer:  w = 20

Capacity remaining = 1,000,000 - 500,000 = 500,000 units
Book value at end of second year = (500,000/1,000,000)*965,500 + 4500
= $487,250
