<span>Express log(2)64-log(2)4 as a single logarithm.
Simplify as possible.
Solution:
= log(2)[64/4]
= log(2)[16]
= 4

The rule for multiplying similar bases with exponents:
(a^b)(a^c)=a^(b+c)
In this case we have:
(5^-2)(5^-1)
5^(-2-1)
5^(-3)
The rule for negative exponents:
a^(-b)=1/(a^b)
So in this case:
5^(-3) is equal to
1/(5^3)
1/125
Answer: 1.9
Step-by-step explanation:
You want to multiply 9x10 which is 90.
Then you want to add 44+pi
now pi can be shown as 3.14 or 22 over 7
in this case you want to add 44 + 3.14 which gives you 47.14
now you want to divide 90/47.14 which gives you 1.90920661858 or in short
1.9
Answer: 8n
Step-by-step explanation: 5n + 3n
The function is definately defined at x=0 but not x=1.
But its just one part of the coordinate (x,y).
If the value of y or f(x) is considered, you'll see that it is never possible to attain f(x)=0. In other terms (x,y)= (0,0) is not a defined point in the graph of the function because the graph doesnt pass through that point.
Now I hope you understood what I meant!
Conclusion- The above function is not defined at all points in the space having the abscissa or x=1 in the coordinate and also at ordinate or y=0 in the coordinate.nation:
