What is the solution of the equation −x2.9=−3

1 answer

To solve the equation −x^2.9 = −3, we can start by isolating the variable x.

We'll begin by multiplying both sides of the equation by -1 to get rid of the negative sign:

x^2.9 = 3

Next, we'll take the 2.9th root of both sides. This is equivalent to raising both sides to the power of 1/2.9:

(x^2.9)^(1/2.9) = 3^(1/2.9)

The exponents on the left side cancel out, leaving us with:

x = 3^(1/2.9)

Using a calculator to approximate the value of 3^(1/2.9), we find that:

x ≈ 1.323

Therefore, the solution to the equation −x^2.9 = −3 is approximately x = 1.323.
