0.0169 x ? = 1.3
Answer: Option
Explanation:
Let 0.0169 x x = 1.3.
Then, 0.0169x = (1.3)2 = 1.69
 x = |

The answer is 100 as x has a square in it when removing the no.
So, finally, when we get 10 as the answer we square 10 as the answer is 100.
So, finally, when we get 10 as the answer we square 10 as the answer is 100.

The given value is 169/10000,so while applying root to the value we get 13/100, i.e;0.13
So if we multiply with 10 .den we get 1.3
ANS=10
So if we multiply with 10 .den we get 1.3
ANS=10

No answer is not 10 because we have remove the square root from 0.0169X
So (1.3)2
then,
0.0169X= (1.3*1.3)
0.0169X=1.69
X=1.69/0.0169
x=169/100/169/10000
then x= 169/100 * 169/10000
x=100 answer
So (1.3)2
then,
0.0169X= (1.3*1.3)
0.0169X=1.69
X=1.69/0.0169
x=169/100/169/10000
then x= 169/100 * 169/10000
x=100 answer

No need to calculate simply how many digit(0)need to get 1.69 from 0.0169 that 2 digit need to move from right side from 0.0169 to left side that much zero need to add to 1.

@Guru.
If you remove the square root from 0.0169X, then why you have squared 1.3 like (1.3)^2.

Hey, Answer must be 100:
13 * 10^(-2) * root(x) = 1.3.
root(x) = 1.3 / (13 * 10^(-2) ).
root(x) = 10.
x = 10 * 10 = 100.
13 * 10^(-2) * root(x) = 1.3.
root(x) = 1.3 / (13 * 10^(-2) ).
root(x) = 10.
x = 10 * 10 = 100.
