Answer:

f(12) = 23

Step-by-step explanation:

f(x) = 2x - 1

f(12) = 2(12) - 1

f(12) = 24 - 1

f(12) = 23

Divide and express the result in standard form. 8/7-i

Gnoma [55]

$i=\sqrt{-1}\to i^2=-1\ (i-the\ imaginary\ unit)\\----------------------\\\\\frac{8}{7-i}\\\\use\ (a-b)(a+b)=a^2-b^2\\\\\frac{8}{7-i}\cdot\frac{7+i}{7+i}=\frac{56+8i}{7^2-i^2}=\frac{56+8i}{49-(-1)}=\frac{56+8i}{49+1}=\frac{56+8i}{50}=\frac{56}{50}+\frac{8}{50}i\\\\=\boxed{\frac{28}{25}+\frac{4}{25}i}$

Answer:

x = 5

Step-by-step explanation:

The equality of bases property says powers of the same base will be equal if and only if the powers are equal. This property is used to solve exponential equations.

<h3>Application</h3>

$\dfrac{(2)^x}{2}=16\qquad\text{copy of the original equation}\\\\2\times\dfrac{(2)^x}{2}=2\times16\qquad\text{multiply by 2 to isolate the base}\\\\2^x=32\qquad\text{simplify}\\\\2^x=2^5\qquad\text{rewrite the constant as a power of 2}\\\\\boxed{x=5}\qquad\text{use the Equality of Bases Property}$

Additional comment

Equating the exponents is fully equivalent to taking the logarithm of both sides of the equation, to that base.

$\log_2(2^x)=\log_2(2^5)\ \Longrightarrow\ x=5$
