I have to solve for x in this problem:

(3x+5)/[(x-1)(x4+7)=0

To solve for x in the equation (3x+5)/[(x-1)(x^4+7)] = 0, you can start by setting the numerator equal to zero:

3x + 5 = 0

Subtracting 5 from both sides:

3x = -5

Next, divide both sides of the equation by 3 to isolate x:

x = -5/3

Now, let's consider the denominator (x-1)(x^4+7). For the fraction to equal zero, either the numerator or the denominator must be equal to zero. Since the numerator is already solved for, we need to solve the denominator:

x - 1 = 0
x = 1

or

x^4 + 7 = 0

To solve the equation x^4 + 7 = 0, we need to subtract 7 from both sides:

x^4 = -7

Then, take the fourth root of both sides:

x = ±√(-7)

However, the square root of a negative number is not a real number, so there are no real solutions for this equation.

Therefore, the solution to the equation (3x+5)/[(x-1)(x^4+7)] = 0 is x = -5/3 or x = 1.
