Answer 2

To solve the equation 9^-5 + x = 729, we can follow these steps:

Step 1: Simplify the left side of the equation. Since 9^-5 means the reciprocal of 9^5, we can rewrite it as 1/(9^5): 1/(9^5) + x = 729

Step 2: Evaluate 9^5. 9^5 = 59049

Step 3: Substitute the value back into the equation. 1/59049 + x = 729

Step 4: Isolate the variable x. Subtract 1/59049 from both sides: x = 729 - 1/59049

Step 5: Simplify the right side. x = 729 - 1/59049 x = (729 * 59049 - 1) / 59049 x = (42857241 - 1) / 59049 x = 42857240 / 59049

Step 6: Simplify the fraction (if possible). The numerator, 42857240, is not divisible by 59049. Therefore, the fraction cannot be simplified further.

So, the solution to the equation 9^-5 + x = 729 is: x = 42857240 / 59049
