Is that 5^x=81.2?
5^x=81.2 take the natural log of both sides
xln5=ln81.2 divide both sides by ln5
x=ln81.2/ln5
x≈2.7320 (to nearest ten-thousandth)
If you just meant 5^x=81, the process is the same
5^x=81 take the natural log of both sides
xln5=ln81 divide both sides by ln5
x=ln81/ln5
x≈2.7304 (to nearest ten-thousandth)
Answer:
The final simplified form would be 6p^2 + 7m
Step-by-step explanation:
In order to find this, we need to start by putting all the like terms together. First, put all the p^2 terms together.
4p^2 + 2p^2 = 6p^2
Then we do the same thing with the m terms.
5m - m + 3m = 7m
Then for the end result, we just put the two terms together.
6p^2 + 7m

Answer:
29
Step-by-step explanation:
Let a12 be the mean of the first 12 numbers:
a12=(sumOf12Numbers)/12.
So, sumOf12Numbers=12×a12
We add a new number, x:
a13=(sumOf12Numbers+x)/13
13×a13=12×a12+x
x=13×a13-12×a12=13×5-12×3=65-36=29
The thirteenth number is 29
