Write 5x-3 in positive index

If you're talking about exponents,

5x^-3 = 5/x^3

If not, please explain "index" to poor ignorant me.

To write 5x - 3 in positive index, we need to rewrite it using exponents.

The positive index form of a number or variable is when the exponent is positive.

In this case, we have 5x - 3. Since there's no exponent explicitly stated, we assume the exponent is 1.

So, we can write this expression in positive index form as 5x^1 - 3^1.

However, since anything raised to the power of 1 is itself, we can simplify this expression further to just 5x - 3.

Therefore, 5x - 3 in positive index form is simply 5x - 3.
