Step-by-step explanation: 18-9 is 9 and 6 times 9 is 54
Logarithm properties:
According to this, we can get:
Answer:
1.
Step-by-step explanation:
Note that 2^4 - 2^3 = 16 - 8 = 8 = 2^3
In a similar way 2^6 - 2^5 = 64 - 32 = 32 = 2^5.
So 2^99 - 2^98 = 2^98 , 2^98 - 2^97 = 2^97 , 2^97 - 2^96 = 2^96 and so on.
Therefore when we come to the last 2 terms we have 2^1 - 2^0 = 2 - 1
= 1 , so the answer is 1.
