Question

a number raised to the fifth power is four less than ten times the number

Answer 1

x^5 = 10x - 4

Answer 2

Let's say the number is x
Then we have:

The number raised to the fifth power: \[x^5\]
Ten times the number: 10*x
Four less that ten times the number: 10*x-4

So the full expression would be:
\[x^5 = 10x-4\]
