Answers
Step-by-step explanation:
meaning of n is 5.
First know this concept,
log base x power x = 1
and log base x power 1= 0
log²log²log³logⁿ125³
=log²log²log³3logⁿ5³
=log²log²log³9logⁿ5
=log²log²log³9
=log²log²log³3²
=log²log²2log³3
=log²log²2
=log²1
=0
Answer:
√64
(1) log₂
6. Express as a single logarithm.
(a)-log36-3log2+1
(c) 5 log (25)

(b) 2 log 5 √5 +3log2 - log 50-1
(160
(d) log (127)
-log
8√√2
3
-log 3+ log(0.6)
If a, b, c are three consecutive natural numbers then log (1 + ac) =
(a) 1
(b) 2
8. log₂ log₂ log, log, 125³ =
(c) 3
(a) 1
9. If log(a + b) = log a + log b, then the value of a in terms of b is
(b) 0
1-b
T (b)
(1+b)
10. If log₂ x + log4x + log16 x then x =
(a) 2
(b) 4
(c) 3
(c) 8
(d) 4
(d) Undefined
b-1
(d) 16
H. If AABC is a right angle triangle, right angle at c, then
logo+ba loge-ba
+
(a) 2
(b) 3
(c) 0
12. If log₂ (x² + x + 1) + log₂ (x - 1) = 3, then x =
13. If log3 x + log, x² + log27 xhenx =
(b) 9
(c) √9
(b) 37
(a) 1
(c) 27
14. Ifa > 1. log(x-2)> loa.5, then the least value of x is
=
(d) 1
(d) a and b
(d) 3
