According to the laws of multiplication, we must first simplify everything into one exercise:
We will simplify and get:
We will simplify and get:
We will factor the expression into a multiplication:
We will simplify and get:
Are the expressions the same or not?
\( 3+3+3+3 \)
\( 3\times4 \)
There's an error in the given explanation! It incorrectly canceled all the m variables. The correct solution keeps one m: , but this doesn't match either answer.
Look for identical factors in both numerator and denominator. In this problem, you can cancel terms, but be careful not to cancel variables that appear with different powers!
Yes! Cancel numerical factors first: , then handle variables:
These are completely different! 0.5m means "half of m" (contains a variable), while 1.5 is just a number. The correct answer should contain m since the original problem has variables.
Pick any value for the variable (like m=2) and substitute it into both the original expression and your answer. If they give the same result, you're correct!
