First, calculate .
The expression is simply .
Taking the absolute value of results in , since the absolute value of a negative number is its positive counterpart.
\( \left|-19\frac{1}{4}\right|= \)
The order of operations matters! You must evaluate what's inside the absolute value bars first. So becomes , then you apply the absolute value.
Great question! , but . They give the same answer here, but the order of operations is different. Always work from inside the absolute value bars outward.
Yes! When the exponent is 1, . The parentheses don't change anything when the exponent is odd. But be careful with even exponents - that's when parentheses matter!
Almost always! The absolute value of any real number is non-negative (positive or zero). Since and , the absolute value gives us .
Then (any non-zero number to the power of 0 equals 1), so . The absolute value of 1 is still 1!
