Log Base 2 8Dcb70

1. **State the problem:** Evaluate the logarithmic expression $$\log_2(4)$$. 2. **Recall the definition of logarithm:** $$\log_b(a) = c$$ means $$b^c = a$$. 3. **Apply the definition:** We want to find $$c$$ such that $$2^c = 4$$. 4. **Express 4 as a power of 2:** $$4 = 2^2$$. 5. **Set the exponents equal:** Since $$2^c = 2^2$$, it follows that $$c = 2$$. 6. **Final answer:** $$\log_2(4) = 2$$.
