Question

if pqr=1 then log r is​

Answer 1

Step-by-step explanation:

pqr=1

r=1/pq

On taking log hoth sides we get,

logr = log(1/pq)

logr = log1 - log pq

logr = - log pq

as we know,

nlogm=m^n

logr= log(pq) ^-1 (ans)

Answer 2

Given: Given expression is pqr=1.

To find: We have to find the value of log r.

Solution:

The expression is pqr=1.

Taking log at both sides of the expression we get-

log(pqr)=log(1)

The multiplication of multiple terms in log result sum of the terms with log and the value of log(1) is 0.

$log(p) + log(q) + log(r) = log(1) \\ log(p) + log(q) + log(r) = 0 \\ log(r) = - ( log(p) + log(q) ) \\ log(r) = - log(pq)$

The value of log r is -log(pq).
