In front of you an algebraic expression:
Replace and calculate
Let's start with the first option.
Let's substitute the given data into the expression:
We'll solve the exercise from left to right, noting that we are first dividing by zero.
Let's remember the rule:
In other words, any number divided by zero will equal zero, therefore:
Now we got the exercise:
Let's continue with the second option.
Let's substitute the given data into the expression:
As we can see, just like in the first option, we are first dividing by zero.
Any number divided by zero will equal zero, therefore we got the exercise:
Therefore the final answer is:
Convert \( \frac{7}{2} \)into its reciprocal form:
0÷a = 0 (zero divided by any non-zero number is zero), but a÷0 is undefined (division by zero is impossible). In our problem, we have , which equals 0.
We must follow PEMDAS/BODMAS! First handle the division , which gives us 0, then add c. If we added c first, we'd get the wrong answer.
When substituting , be careful with signs! The expression becomes . Remember: negative divided by negative equals positive.
No! Since we're dividing zero by any non-zero number, the result is always 0. Whether the denominator is or simplified doesn't matter - zero divided by anything (except zero) equals zero.
