Use the properties of logarithms Rewrite the following in the form log(c). 5log(2)

Alecsey [184]

Answer: $5\log(2)=\log(2^5)$

Step-by-step explanation:

According to the properties of logarithms, we have

To rewrite : $5\log (2)$ in the form of log(c).

Therefore,

$\leq 5\log(2)=\log(2^5)$ [ $\because\ n\log(m)=\log(m^n)$ ]

Hence, $5\log(2)=\log(2^5)$ .

Perform the indicated operation.(3/a+2) + (4/a-5)

kipiarov [429]

Answer:

$\frac{7(a-1)}{(a+2)(a-5)}$

Step-by-step explanation:

To solve this operation we need to find the common multiple of both denominators and solve for a.

$\frac{3}{a+2} + \frac{4}{a-5} =\frac{3(a-5)+4(a+2)}{(a+2)(a-5)} =\frac{3a-15+4a+8}{(a+2)(a-5)} =\frac{7a-7}{(a+2)(a-5)} =\frac{7(a-1)}{(a+2)(a-5)}$

Thus, the solution is 7(a -1) / (a+2)(a-5)
