A computer with a 32-bit virtual address uses a two-level page table. Virtual addresses are split into a 10-bit top-level page table field (PT1), a 10-bit second-level page table field (PT2), and an offset. \nHow many PT1, PT2, and offsets are there with the virtual address $0x00403008$ or $0000\ 0000\ 0100\ 0000\ 0011\ 0000\ 0000\ 1000$?
