Understanding (-1/2)^8
In mathematics, exponents indicate how many times a base number is multiplied by itself. In this case, we have (-1/2)^8, which means we multiply (-1/2) by itself 8 times.
Calculating the Result
-
Step 1: Even Exponent: Notice that the exponent (8) is even. This is crucial because an even exponent applied to a negative base results in a positive answer.
-
Step 2: Individual Multiplication: We can simplify the calculation by first considering the numerator and denominator separately.
- (-1)^8 = 1 (any negative number raised to an even power becomes positive)
- (2)^8 = 256
-
Step 3: Combining the Results: Combining the results, we get:
(-1/2)^8 = (-1)^8 / (2)^8 = 1 / 256
Conclusion
Therefore, (-1/2)^8 is equal to 1/256.
