Understand the problem

(5)1= |(-5)^1| =

2

Step-by-step solution

First, calculate (5)1(-5)^1.

The expression (5)1(-5)^1 is simply 5-5.

Taking the absolute value of 5-5 results in 55, since the absolute value of a negative number is its positive counterpart.

Final Answer

5 5

Key Points to Remember

Essential concepts to master this topic
  • Rule: Evaluate the exponent first, then apply absolute value
  • Technique: (5)1=5 (-5)^1 = -5 , then 5=5 |-5| = 5
  • Check: Absolute value always gives non-negative result: (5)1=50 |(-5)^1| = 5 ≥ 0

Common Mistakes

Avoid these frequent errors
  • Applying absolute value before evaluating the exponent
    Don't convert (5)1 |(-5)^1| to 51=5 |5|^1 = 5 by removing the negative first! This changes the base incorrectly. Always evaluate the exponent completely first: (5)1=5 (-5)^1 = -5 , then take absolute value: 5=5 |-5| = 5 .

FAQ

Everything you need to know about this question

Why don't I just ignore the negative sign since there's absolute value?

+

The order of operations matters! You must evaluate what's inside the absolute value bars first. So (5)1 (-5)^1 becomes 5 -5 , then you apply the absolute value.

What's the difference between (5)1 |(-5)^1| and 51 |-5|^1 ?

+

Great question! (5)1=5=5 |(-5)^1| = |-5| = 5 , but 51=51=5 |-5|^1 = 5^1 = 5 . They give the same answer here, but the order of operations is different. Always work from inside the absolute value bars outward.

Does (5)1 (-5)^1 equal 51 -5^1 ?

+

Yes! When the exponent is 1, (5)1=51=5 (-5)^1 = -5^1 = -5 . The parentheses don't change anything when the exponent is odd. But be careful with even exponents - that's when parentheses matter!

Will the absolute value always make my answer positive?

+

Almost always! The absolute value of any real number is non-negative (positive or zero). Since (5)1=5 (-5)^1 = -5 and 5<0 -5 < 0 , the absolute value gives us 5>0 5 > 0 .

What if the exponent was 0 instead of 1?

+

Then (5)0=1 (-5)^0 = 1 (any non-zero number to the power of 0 equals 1), so (5)0=1=1 |(-5)^0| = |1| = 1 . The absolute value of 1 is still 1!
