Answer: 

Step-by-step explanation:
The given function : 
When we substitute x= -64, we get

Since , 
So, 
That means 

i.e. 
Similarly, When we substitute x= 64, we get

Since , 
That means 

i.e. 
A) x= 5
b) x= 1
basically, 5x5x5=125 so that mean 5 to the power of 3 equals 125. This says x-2, so 5-2=3 which completes the equation of 5 to the power of 3. same with the second one.
Answer: 542
Step-by-step explanation:
The quotient is known as the final answer gotten after the value of 4878 has been divided using 9. The answer as such will be 542 (i.e 4878/9)
9 goes in 48 five times, 5 is written and remainder of 3 is kept above 7 to make it 37; then 9 goes in 37 four times, 4 is written and the reminder of 1 is written above 8 to make it 18; and finally 9 goes in 18 two times without remainder, then we write 2. Combining the answers gives our Final answer 542.
