Step-by-step explanation:

my option b)5

and answer

Answer 2

Step-by-step explanation:

answer is 6

I explain you

(45/10)*(45/10)=2025/100

(36/10)*(36/10)=1296/100

(9/10)*(9/10)=81/100

(5/10)*(5/10)=25/100

let the unknown number be x

on multipling and cancelling the 2025/100*1296/100=81*324/100

81/100*25/100==81/400

(81*324/100) / ( 81/400*(x)power 4 )=

81*324*400/100*81*(x) power 4=

81*4*4 / (x)power 4=

1296/(x) power 4=1

1296=(x)power 4

4th root of 1296=x

so x = 6
