Question

write log 10+2 log 3 - log 2 as 'LogN' and find their value​

Answer 1

Answer:

Step-by-step explanation:

log a+logb= logab

alogb= log(b^a)

loga-logb=log(a/b)

using these we get

log10+log9-log2

log(90/2)

=log45

Answer 2

Step-by-step explanation:

$log(10) + 2 log(3) - log(2) \\ = log( \frac{10 \times 9}{2} ) \\ = log(45)$

N = 45
