Which is larger?
To solve this problem, we need to follow these steps:
Now, let's proceed with these steps:
Step 1: Evaluate the expression .
The inner expression is . Calculating this gives:
Next, we compute the expression , which simplifies to:
Finally, we square this result:
Thus, the value of the first expression is 729.
Step 2: Evaluate the expression .
First, calculate :
Next, raise this result to the fourth power:
Thus, the value of the second expression is 256.
Step 3: Compare the two results from above:
We have and .
Since 729 is greater than 256, the expression is larger.
Thus, the correct answer is .
\( (-2)^7= \)
When you raise a negative number to an odd power, the result stays negative! . Remember: odd powers keep the sign, even powers make it positive.
A negative times a negative equals positive! So . Think of it as "the opposite of negative 27" which is positive 27.
Be careful! You can use it for . But for , you must evaluate the inner expression first because of the negative signs.
Work from the inside out, one layer at a time. Write each step clearly:
The first expression simplifies to , while the second becomes . Even though 4 is bigger than 27, raising 27 to the 2nd power gives a larger result than raising 4 to the 4th power!
