Answer:

The answer is "4.3".

Step-by-step explanation:

Given:

$\to x^3 - 5x - 59 = 0$

When $x = 4.1:$

$\to f(4.1) = (4.1)^3 - 5(4.1) - 59 = -10.579$

When $x= 4.2:$

$f(4.2) = 4.2^3 - 5(4.2) - 59 = -5.912$

When $x = 4.3:$

$\to f(4.3) = -0.993$ (closer to 0)

$\to f(4.4) = 4.184$

It changes the sign so, the root lies in 4.3 and 4.4.

When $x = 4.35:$

$\to f(4.35) = 1.563$

When the root is closer to 4.3 than 4.4 So, 1.563 is closer to zero than 4.184.

When $x = 4.32:$

$\to f(4.32) = 0.0216$ close to zero.

So the answer is 4.3 to 1 decimal place.
