log3 (q) x logp (81) x logq (p^3q) = 9
log3 (q) x log3 (81) ÷ log3 (p) x 3q log3 (p) ÷ log3 (q)= 9
log3 (81) x 3q = 9
log3 (3⁴) x 3q = 9
4 x 3q = 9
q = 9/12
= 3/4
you have to make use of the property loga (b) = logc (b) / logc (a)
log3 (q) x log3 (81) ÷ log3 (p) x 3q log3 (p) ÷ log3 (q)= 9
log3 (81) x 3q = 9
log3 (3⁴) x 3q = 9
4 x 3q = 9
q = 9/12
= 3/4
you have to make use of the property loga (b) = logc (b) / logc (a)
how to find the value of another unknown? thanks a lot
Don't have to find. Any real value of p will do provided p > 0, p,≠ 1
