Is it true that ƒ −(g − h) = (ƒ − g) − h? Explain why you believe the equation is true or provide a counterexample to show that

miss Akunina [59]

Answer:

The expression is false

Step-by-step explanation:

Given

$f - (g - h) = (f - g) - h$

Required

True or False

To determine if the expression is true or false, we need to simplify both sides of the equation

$f - (g - h) = (f - g) - h$

<em></em>

<em>Start by opening the bracket on the right hand side</em>

<em></em> $f - (g - h) = f - g - h$ <em></em>

<em></em>

<em>Then open the bracket on the left</em>

<em></em> $f - g + h = f - g - h$ <em></em>

<em></em>

<em>Subtract f - g from both sides</em>

<em></em> $f - g - (f - g) + h = f - g - (f - g) + h$ <em></em>

<em></em> $f - g - f + g + h = f - g - f + g - h$ <em></em>

<em></em> $f - f - g + g + h = f - f - g + g - h$ <em></em>

<em></em> $h \neq -h$ <em></em>

<em></em>

<em>Hence;</em>

<em>The statement is false</em>

<em></em>

<em>To further check;</em>

<em>Assume f = 5; g = 4 and h = 3</em>

$f - (g - h) = (f - g) - h$ becomes

$5 - (4 - 3) = (5 - 4) - 3$

$5 - 4 + 3 = 5 - 4 - 3$

$2 \neq -2$
