How to use SRL and SLL command

how to use srl and sll command?
for example .... i want to shift 12345678 to 00001234

Lui t0 $1234
Ori t0 t0 $5678
Srl t1 t0 16

t1 = 0x00001234

Srl x y z

x = register to hold result
y = register that holds the value to shift to
z = number of digits to shift to * 4

thx alot ... that helps
u making videos for that 2?

My goal is to cover every MIPS command in the current play list I am working on.
