Question

Which of the following is the solution to the equation sqrt5^8n = 125^(n +3)

Answer 1

Did u mean this? \[\sqrt{5^{8n}} = 125^{n+3}\]

Answer 2

the 8n is outside of the sqrt function, but the 125^(n+3) you entered looks right

Answer 3

\[\sqrt{5}^{8n}=125^{n+3}\]like this?

Answer 4

exactly!

Answer 5

\[\sqrt{5}^{8n}=125^{n+3}\]

Answer 6

\[\sqrt{5}^2=5\],
\[5^3=125\] so
\[\sqrt{5}^6=125\] is a start

Answer 7

my choices are n = –9

n = 9

n = –3

n = 3

Answer 8

n = 9

Answer 9

opps...and also -9

Answer 10

put
\[8n=6(n+3)\] amd solve for n

Answer 11

n = 9

Answer 12

Thanks so much!
