40²+B²=25²

Answer 1

It seems you are given a Pythagorean theorem-like equation:

40² + B² = 25²

Let's solve for B²:

(40)² + B² = (25)²

1600 + B² = 625

To find B², subtract 1600 from both sides of the equation:

B² = 625 - 1600

B² = -975

The result is negative, which implies that B² is not the square of a real number, because the square of any real number must be non-negative. If you are looking for a real number solution, there might be a mistake in the equation as it was presented. However, if you are looking for a complex number solution, then B would be a complex number with an imaginary part. To find the value of B in that case:

B = √(-975)

B = i√(975)

Where 'i' is the imaginary unit, which is defined as the square root of -1.
