2 logbq + 8 logbt
= logb (q2) + logb (t8)
= logb ( q2t8)
2. Using the properties of logarithm
4 log x – 6 log (x + 2)
= log x4 – log (x + 2)^6
= log ( x4/ ( x + 2)^6)
So the answer is not in the choices

Find the missing numerator in each of the following fractiions? A. 5/6= /12. B. 2/4= /36. C. 2/5=/20. D. 4/25=/100

lesantik [10]

Answer:

A. 10

B. 18

C. 8

D. 16

Step-by-step explanation:

We are given a number of incomplete fractions and we are to find the missing numerator in each one of these.

To find the missing numerator or denominator, we multiply the numerator and the denominator by the same number to get an equivalent fraction.

A. $\frac{5}{6} =\frac{10}{12}$

Here the denominator is multiplied by 2 so the denominator will also be multiplied by 2 to get 10.

B. $\frac{2}{4} =\frac{18}{36}$

Numerator is multiplied by 9.

C. $\frac{2}{5} =\frac{8}{20}$

Numerator is multiplied by 4.

D. $\frac{4}{25} =\frac{16}{100}$

Numerator is multiplied by 4.
