Question

(x2 1/4)*4/5=0помогитеееее

Answer 1

х^2*0.25*0.8=0

x=√0.2

Answer 2

Sure, I'd be happy to help you with this math problem! Let's solve it step by step:

The expression you provided is:

(x^2 + 1/4) * (4/5) = 0

To find the value of 'x,' we need to isolate it on one side of the equation. First, let's get rid of the fraction (4/5) by multiplying both sides of the equation by (5/4):

(5/4) * (x^2 + 1/4) * (4/5) = 0 * (5/4)

Simplify:

(x^2 + 1/4) = 0

Now, let's isolate 'x^2' by subtracting 1/4 from both sides of the equation:

x^2 = -1/4

Finally, to solve for 'x,' take the square root of both sides:

x = ±√(-1/4)

The square root of a negative number is a complex number, and √(-1) is represented by 'i' in complex numbers. So, the solution is:

x = ± (i/2)

Please note that the result is in complex numbers since there is no real number that satisfies the original equation (x^2 + 1/4) * (4/5) = 0.
