Solution by Steps
step 1
To find the smallest positive integer solution, we start by solving the inequality (100,000,000x4)<1\left(\frac{100,000,000}{x^{4}}\right)<1
step 2
Multiply both sides of the inequality by x4x^4 to get 100,000,000<x4100,000,000 < x^4
step 3
Take the fourth root of both sides to find x>100,000,0004x > \sqrt[4]{100,000,000}
step 4
Calculate the fourth root of 100,000,000 to get x>100x > 100
step 5
Since we are looking for the smallest positive integer solution, the answer is the smallest integer greater than 100, which is 101
Answer
101
Key Concept
Solving Inequalities Involving Powers
Explanation
To solve the inequality, we isolated the variable by multiplying both sides by x4x^4 and then took the fourth root to find the range of solutions. We then identified the smallest integer greater than 100 to find the smallest positive integer solution.
