Answer:

x = 0.96

Step-by-step explanation:

$7 \times 16^{8x - 8} = 3$

$(2^4)^8(x - 1) = \dfrac{3}{7}$

$2^{32(x - 1)} = \dfrac{3}{7}$

$\log 2^{32(x - 1)} = \log \dfrac{3}{7}$

$32(x - 1)\log 2 = \log 3 - \log 7$

$(x - 1) = \dfrac{\log 3 - \log 7}{32}$

$(x - 1) = \dfrac{\log 3 - \log 7}{32\log 2}$

$x = \dfrac{\log 3 - \log 7}{32\log 2} + 1$

$x = 0.961800237...$

Answer: x = 0.96

What is the sum? 3k/k^2+k-7/4K

Aleksandr-060686 [28]

Answer:

$\dfrac{k^2+5k}{4k^2}$

Step-by-step explanation:

A suitable common denominator is 4k^2. (This eliminates the first and last choices.)

$\dfrac{3k}{k^2}+\dfrac{k-7}{4k}=\dfrac{4(3k)}{4(k^2)}+\dfrac{k(k-7)}{k(4k)}\\\\=\dfrac{12k+k^2-7k}{4k^2}=\boxed{\dfrac{k^2+5k}{4k^2}}$
