Evaluate Exponent: Evaluate the first term (21)−2 by finding the reciprocal of (21)2. A negative exponent means that we take the reciprocal of the base raised to the positive of that exponent. (21)−2=(12)2
Calculate Fraction Square: Calculate the square of 12.When we square a fraction, we square both the numerator and the denominator.(12)2=22/12=14=4
Evaluate Zero Exponent: Evaluate the second term 30. Any non-zero number raised to the power of 0 is 1. 30=1
Add Calculated Values: Add the results from Step 2 and Step 3.Now we add the two values we have calculated.4+1=5
