What is the value of log625^5? A: -4 B:-1/4 C:1/4 D:4

shtirl [24]

Answer:

The value of $log_{625}(5)$ is $\frac{1}{4}$

Step-by-step explanation:

We want to evaluate $log_{625}(5)$ .

The base of this logarithm is $625$ and the number is $5$ .

We need to express the number $5$ as the base $625$ raised to a certain index.

This implies that, $log_{625}(5)=log_{625}(625^{\frac{1}{4}})$

Recall now that,

$log_a(m^n)=nlog_a(m)$ .

We apply this property to obtain,

$log_{625}(5)=\frac{1}{4}log_{625}(625)$

Recall again that,

$log_a(a)=1,a\ne0\:or\:1$ .This implies that,

$log_{625}(5)=\frac{1}{4}(1)$

$log_{625}(5)=\frac{1}{4}$

The correct answer is C.

PLEASE FOLLOW THE DIRECTIONS AND SHOW YOUR WORK. IM OFFERING 15PTS (Way more than its worth) AND BRAINLIEST ANSWER. PLEASE HELP

Alex

I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.

a. $x+y=425, x-y=25$

b. I will solve your system using substitution.
$x+y-425, x-y=25$
Step 1: Solve $x+y=425$ for x
$x+y+-y=425+-y$ (add -y for both sides)
$x=-y+425$
Step 2: substitute $-y+425$ for x in $x+b=25$
$x+y=25$
 $-y+425-y=25$
$-2y+425=25$ (simplify both sides of the equation)
$-2y+425+-425=25+-425$ (add -425 to both sides)
 $-2y=-400$
$\frac{-2y}{-2} = \frac{-400}{-2}$
y=200
step 3: substitute 200 for y in $x=-y+425$
$x=-y+425$
$x=-200+425
$
$x=225$
$x=225, y= 200$

c. Already answered with the picture that is attached.

d. Gavin earned 225 dollars while Seiji earned 200 dollars.
