Explanation:

Solving (a): To base 10

We simply multiply each digit by a base of 16 to the power of their position.

i.e.

In hexadecimal

So:

This gives:

In hexadecimal

So:

Solving (b): To base 10

We simply multiply each digit by a base of 2 to the power of their position.

i.e.

Solving (c): To base 16

First, convert to base 10

In (b)

Next, is to divide 781754 by 16 and keep track of the remainder

Write out the remainder from bottom to top

In hexadecimal

So:

In b

Next, is to divide 11057389 by 16 and keep track of the remainder

Write out the remainder from bottom to top

In hexadecimal

So:

Solving (d): To octal

Divide 74510 by 8 and keep track of the remainder

Write out the remainder from bottom to top

Divide 67210 by 8 and keep track of the remainder

Write out the remainder from bottom to top
