Question

Please help, I will medal and Fan best answer:
A number to the 12th power divided by the same number to the 9th power equals 125. What is the number?

Answer 1

Omg I'm latterly on the phone and solving this question in my mind so this is a rational equation
X^12/x^9 = 125
X= 5

Answer 2

If it doesn't make sense simplify you'll get
X^3 = 125
Apply cube root and you'll get x= 5

Answer 3

Write it in this form:\[\frac{ x^{12} }{ x ^{9} } = 125\]
X is the number you are trying to find.
This can be simplified to:
\[x ^{12-9}=125\rightarrow x ^{3}\]

Answer 4

sorry, my computer's kinda slow, thanks 2 both of u : )

Answer 5

What number cubed is 125? To find this, cube root both sides:
\[x=\sqrt[3]{125} = 5\]
