Which of the following is the value of (4/5)^{9} / (4/5)^{9}?
(64)^{}^{3/2} = ( 8 )^{2 x  3/2} = (8)^{3 }
= 1 / (8)^{3} = 1/ 512
So option B is correct answer .
Given,
[3^{(x3)}] 5^{(x4)} = 45 = 3^{2} (5^{1})
On comparing both sides we get,
x3 = 2 and x4 = 1
=> x = 5
Hence, option A is the correct answer.
(4²)^{3/2} = (4)^{3/2 ×2} = (4)³ = 64
How many zeros after the decimal point will be there in the decimal form of the number 10^{n} ?
(16)^1/4 × 4√16 =(16)^1/4 × (16)^1/4 =(16)^1/4+1/4 =(16)^0 = 1.
It's 1 because of a^{0}= 1.
So 1×1/1 = 1
(1)^{1 }=  1 / 1 = 1
81^{1/2 } can be written as (9) ^{2x1/2} = 9
49^{1/2 }can be written as (7)^{2x1/2} = 7
( 5 ) ^{3 x 1/3 } x ( 5 ) ^{2 x }^{1/2 }
( 5 ) ^{1 }x ( 5 ) ^{ 1}
1 / 25
