I need help I don’t know how that’s not right.

Leviafan [203]

Answer: v=-81.92

Step-by-step explanation:

$\displaystyle\\7+\frac{v}{8} =-3.24\\\\7+\frac{v}{8}-7 =-3.24-7\\\\\frac{v}{8} =-10.24\\\\\frac{v}{8} =-10.24$

Multiply both parts of the equation by 8:

$\displaystyle\\(\frac{v}{8})(8)=(-10.24)(8) \\\\v=-81.92$

Use the change of base formula to evaluate log3(73).

Marrrta [24]

The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,

$log_{a}x = \frac{ log_{b}x }{log_{b}a }$

where a≠1 and b≠1

Assigning the base to be 7,

$log_{3}73 = \frac{ log_{7}73 }{log_{7}3 }=3.9$

I hope I was able to answer your question. Have a good day.
