What Will Be The Equi Valent Resistance Of The Resistor R1 R2 Connected In Parallel?

What Will Be The Equi Valent Resistance Of The Resistor R1 R2 Connected In Parallel? Likewise, if three or more resistors each with the same value are connected in parallel, then the equivalent resistance will be equal to R/n where R is the value of the resistor and n is the number of individual resistances
