Evaluate the logarithm.<br> log2 16

solong [7]

Answer:

$log_2 (16) = 4$

Step-by-step explanation:

Here, the given expression is:

$log_2 (16)$

Now,as we know:

$log_b(b^k) = k$

Now, $log_2 (16) = log_2 (2^{(4)})$

Applying this to the given expression, we get:

$log_2 (2^{(4)}) = 4$ where: b = 2, and k = 4

Hence, $log_2 (16) = 4$

What is the value of c in the equation below?

Rudik [331]

Answer:

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ and $a^{-m}$ = $\frac{1}{a^{m} }$

Given

$2^{-4}$ × 2² = $2^{(-4+2)}$ = $2^{-2}$ = c , hence

c = $2^{-2}$ = $\frac{1}{2^{2} }$ = $\frac{1}{4}$ → D

What is the solution to the equation StartFraction 3 Over m + 3 EndFraction minus StartFraction m Over 3 minus m EndFraction = S

Oksanka [162]

Answer:

No solution.

Step-by-step explanation:

Given fraction is:

$\dfrac{3}{m+3} -\dfrac{m}{3-m} = \dfrac{m^2+9}{m^2-9}\\\Rightarrow \dfrac{3}{m+3} +\dfrac{m}{m-3} = \dfrac{m^2+9}{m^2-9}\\\Rightarrow \dfrac{3\times (m-3)+ m(m+3)}{(m+3)(m-3)} = \dfrac{m^2+9}{m^2-9}\\\Rightarrow \dfrac{3 m-9+ m^2+3m}{m^2-9} = \dfrac{m^2+9}{m^2-9}\\\Rightarrow \dfrac{m^2-9+ 6m}{m^2-9} = \dfrac{m^2+9}{m^2-9}\\If\ m^2-9 \neq 0\ or\ m \neq 3\\\Rightarrow m^2-9+ 6m = m^2+9\\\Rightarrow 6m = 18\\\Rightarrow m = 3$

But, the above equation was solved at the condition that:

$m\neq 3$

So, there is no solution for the given equation.
