How do you solve, 5 ^3x-4/25=625​

Mathematics
1 answer:
gtnhenbr [62]3 years ago
3 0

Step-by-step explanation:

(5^3x*25-4)/25=625

125^3x-4=625*25

5^x-4=15625

5^x=15625-4

5^x=15621 I can't solved by me if there is only 15625 then the answer will be 6 because 5^6=15625 but there is -4 too

algol [13]
-3\frac{2}{3}\cdot\left(-2\frac{1}4{}\right)=\\--------------------\\negative\ number\ multiply\ by\ negative\ number\ is\ a\ positive\ number\\--------------------\\-3\frac{2}{3}\cdot\left(-2\frac{1}4{}\right)=3\frac{2}{3}\cdot2\frac{1}{4}=\\------------------------------\\

if you want to multiply mixed numbers you need to turn them into improper fractions

3\frac{2}{3}\cdot2\frac{1}{4}=\frac{3\cdot3+2}{3}\cdot\frac{2\cdot4+1}{4}=\frac{9+2}{3}\cdot\frac{8+1}{4}=\frac{11}{3}\cdot\frac{9}{4}=\frac{11}{1}\cdot\frac{3}{4}=\frac{11\cdot3}{1\cdot4}\\\center\boxed{=\frac{33}{4}=8\frac{1}{4}}

Let f(x)=−log(4x)+5.
Aloiza [94]
To solve the average rate of change, use the formula of the slope:
m = ( y2 - y1 ) / ( x2 - x1 )
but first we must solve the value of the function when x = 3

f(3) = - log ( 4 * 3 ) + 5
f (3) = 3.92

solve the function when x = 8
f(8) = - log ( 4 * 8) + 5
f(8) = 3.49

so the average rate of change
m = ( 3.49 - 3.92 ) / ( 8 - 3)
m = - 0.09
