MIPs Assembly Language

Hello all, I was wondering if i could get some clarification. Machine code consists of bits(0s,1s), machine instructions example add $t0, $s0, $s2 etc. 3 types of formats I(opcode is not all 0 and does not equal 2 or 3), R(opcode is all 0s), J(opcode is 2 or 3). When asked to for the machine code in hex, hex always starts with 0x or it doesnt matter? So i have a problem where its asking for the type of format of the instruction bne t0 zero LESS and its i type with opcode in hex being 0x5, rs in hex being 0x8, rt in hex being 0x0. The name of the traget label is LESS and its address is 0x0040001c. The question I have is do we put the branchs address in the immediate field? Im assuming we need to convert the branch to bits in order to fill it in the immediate field. How would we obtain the value of the immediate field(LESS)? Do i look at the data table or how do i go about this?

bne $t0, Szero, LESS 17 18 19 # Ips 1 part 20 j GPEO 20 21 22 23 LESS: #load # load li $v0, 4 la $al, strl syscall END 24 25
