To see the first parallel connection, it can help to re-draw the circuit as follows.

Now, R3 and R4 should appear to be in parallel. Don't worry, I didn't change the circuit! I just moved the resistors around while keeping the connections the same.

Solve for the equivalent resistance (REQ1) of R3 and R4 in parallel:

Re-draw the circuit to show R3 and R4 replaced by REQ1:

REQ1 and R2 are in series, so we add their values together to get REQ2:

Re-draw the circuit again replacing REQ1 and R2 with REQ2:

Now, REQ2 and R5 are in parallel. Find the equivalent resistance for those two (rounding to 2 decimal places):

Once again, re-draw the circuit to show REQ3:

Almost done! We just have one more resistance to compute. Add REQ3 to R1 to get the final equivalent resistance (REQ):

And that's it! The total equivalent resistance for the whole circuit is 2924.76 Ω.
