5⁶+⅞-1

To solve this expression, let's break it down step by step:

Step 1: Calculate 5 raised to the power of 6 (5⁶): 5⁶ = 5 * 5 * 5 * 5 * 5 * 5 = 15,625

Step 2: Add 7/8 to the result from Step 1: 15,625 + 7/8

Since 7/8 is a fraction, we need to find a common denominator to add it with a whole number. In this case, the common denominator is 8.

Step 3: Convert the whole number to a fraction with the denominator of 8: 15,625 = 15,625/1

Step 4: Add the fractions: 15,625/1 + 7/8 = ((15,625 * 8) + 7)/(1 * 8) = (125,000 + 7)/8 = 125,007/8

So, the final solution is 125,007/8.
