Question

if P upon Q is equal to 5 upon 6 raise to power minus 2 X 4 upon 3 raise to power zero find the value of P upon Q raise power 0​

Answer 1

Given :   P/Q  =  (5/6)⁻²    x   (4/3)⁰  

To Find :    (P/Q)⁰

Solution:

P/Q  =  (5/6)⁻²    x   (4/3)⁰  

=> P/Q  =  (6/5)²    x   (4/3)⁰

as a⁻ⁿ  =  1/aⁿ    or aⁿ = 1/a⁻ⁿ

any number raised to power 0 is 1

=> P/Q  =  (6/5)²    x  1

(a/b)ⁿ  = aⁿ/bⁿ

=>  P/Q  =   36/25

P/Q  =   36/25

 (P/Q)⁰  = (36/25)°

=>  (P/Q)⁰  =  1
