Ab=81, a=81/b
s=a+b using a from above in this we get:
s(b)=81/b +b
s(b)=(81+b^2)/b
ds/db=(2b*b-81-b^2)/b^2
ds/db=(2b^2-81-b^2)/b^2
ds/db=(b^2-81)/b^2
d2s/db2=(2b^3-2b^3+81)/b^4
d2s/db2=81/b^4 since b is positive we know that the acceleration is positive so that when ds/db=0 it is a minimum for s(b)
ds/db=0 only when b^2-81=0, b^2=81, b=9
The two positive numbers are 9 and 9.
Simplify things
15(82) = 1230
15 / 1230 = 15/ (15*82)
hence =1/82
Percent error=100*(measurement-actual dimension)/actual dimension
pe=100(5.12-6)/6=-14.67%
So there is a 14.67% error.
-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)
