Solve the following exercise:
36416=x2
To solve the problem 36416=x2, we proceed step-by-step as follows:
- First, we simplify 364. Since 64=43, it follows that 364=4.
- Next, simplify the expression 36416:
416=4.
- Now, take the square root of this simplified value. Thus, 4=2.
- The equation simplifies to: x2=2. Since x2=∣x∣, we have ∣x∣=2.
- This implies x=2 or x=−2.
- However, choices include only positive solutions, and thus x=2.
Therefore, the solution to the problem is x=2.
