Answer:
z = (xy)/(x+y)
Step-by-step explanation:
Taking logarithms base 10, we have ...
x·log(2) = y·log(5) = z·log(10)
z = x·log(2) = y·log(5) . . . . . . . . log(10) = 1
__
Then z/x = log(2), and z/y = log(5), so ...
z/x +z/y = log(2) +log(5) = log(2·5) = 1
z = 1/(1/x +1/y) = 1/((x+y)/(xy))
z = (xy)/(x+y)
Answer:
Divide: 2 : 1
8
= 2
1
· 8

= 2 · 8
1 · 1
= 16

= 16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
8
is 8
1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
In words - two divided by one eighth = sixteen.
