To convert the numeral 7001eight to base ten, you need to multiply each digit by the corresponding power of eight and then sum them up.

In this case, the numeral is already given in base eight (denoted by the subscript eight), so we can use the following formula:
7001eight = 7 * 8^3 + 0 * 8^2 + 0 * 8^1 + 1 * 8^0

Calculating the powers of 8:
8^3 = 8 * 8 * 8 = 512
8^2 = 8 * 8 = 64
8^1 = 8
8^0 = 1

Now we substitute these values into the formula:
7001eight = 7 * 512 + 0 * 64 + 0 * 8 + 1 * 1

Multiplying and summing:
7001eight = 3584 + 0 + 0 + 1

Finally, adding all the terms together, we get:
7001eight = 3585

Therefore, the numeral 7001eight is equal to 3585 in base ten.
