Question

32 by 243 whole to the power of n is equal to 8 by 27 then find n + 0.4 by 1024 whole to the power of minus n​

Answer 1

Step-by-step explanation:

(32/243)^n = 8/27

2^5n /3^5n= 2^3/3^3

(2/3)^5n=(2/3)^3

5n=3

n=3/5

n=0.6

then

{(n+0.4)/1024}^-n

= {(0.6+0.4)/1024}^-0.6

= (1/1024)^-0.6

=( 1024)^0.6

={2^10}^6/10

=(2^6)
