Answer:
(y - x)/(y + x)
Step-by-step explanation:
(1/x - 1/y)/(1/x + 1/y) =
= (1/x - 1/y)/(1/x + 1/y) × (xy)/(xy)
= (y - x)/(y + x)
Answer:
b = 
Step-by-step explanation:
Using the rule of logarithms
log
⇔ nlogx
Given
190 =
( take the natural log ln of both sides )
ln190 = ln
= bln200 ( divide both sides by ln200 )
= b
