What is the smallest positive integer solution to $(100,000,000 \div x^4 ) < 1$?
I need to find the smallest value of x that makes the fraction less than 1, which means that the numerator has to be smaller than the denominator. I can rewrite the fraction as $(10^8 \div x^4) < 1$, and then multiply both sides by $x^4$ to get $10^8 < x^4$. To get rid of the exponent on x, I can take the fourth root of both sides, which gives me $10^2 < x$. This means that x has to be greater than 100, and the smallest possible integer that satisfies this condition is 101. Therefore, the smallest positive integer solution is x = 101.
