Question 2

Time: 00:00:00
If ax = by, then express in terms of x/y:-

log(a/b) = x/y

log(a/b) = x/y

log(a) / log(b) = x/y

log(a) / log(b) = x/y

log(a) / log(b) = y/x

log(a) / log(b) = y/x

None of these

None of these

Question 3

Time: 00:00:00
If log8 x + log8 (1/6) = 1/3 then, the value of x will be:

18

24

24

Question 4

Time: 00:00:00
If log x + log y = log (x + y), then which statement follows:

y = x/(x-1)

y = x/(x-1)

xy=1

xy=1

y = (x-1)/x

y = (x-1)/x

x = y

x = y

Question 5

Time: 00:00:00
If log10 7 = a, then log10(1/70) will be equal to:

1/10a

1/10a

(1 +16 a)-1

(1 +16 a)-1

a/10

a/10

-(1 + a)

-(1 + a)

Question 6

Time: 00:00:00
If log{(a+b)/3} = 0.5(log a + log b), then the correct relation between a and b will be:

a^{2}+b^{2}= 7ab

a^{2}+b^{2}= 7ab

a^{2}-b^{2} = 7ab

a^{2}-b^{2} = 7ab

(a+b)2 = 2

(a+b)2 = 2

(a+b)/3 = (1/2)(a+b)

(a+b)/3 = (1/2)(a+b)

Question 7

Time: 00:00:00
If log x = log 3 + 2 log 2- (3/4) log 16. The value of x will be:

4
