. We're sorry about the hassle.
Sorry but i guess that (sqrt)X^2 = +X and NOT -X .Correct me if i am wrong.

Consider 2 real nos, x and ( − x ) . Now, if you square them, you get x 2 for both of them. So, from definition of square root, we can say both x and ( − x ) are square roots of x 2 . Actually, when we generally square root a number x , we generally take the principal positive square root as the answer but mathematically both the positive and the negative values are correct answers.
So, if a = b and d = b a ,
then, d = a a = 1
hence, C = d a b = 1 a 2 = a
therefore, C = 2 3 4 − 3 4 + 9 = 2 0 + 9 = 1 + 9 = 1 0 ←
Very very simple.
34-34=0
Simple so far???? Good.
2 to the power of zero=1
(Any number to the power of zero is 1, don't ask me how.)
1+9=10
See!! I told you it was easy!!!
a=10
b=a, or b=10
d=a/b
d=10/10
d=1
Look at how simple this is!!
c= square root of ab/d
c= square root of 10*10/1
c=square root of 100/1
c=10/1
C=10
2 3 4 − 3 4 = 2 0 = 1 , thus a = 1 + 9 = 1 0
b = a , so b = 1 0
b a = 1 0 1 0 = 1 , thus d = 1
a b = 1 0 × 1 0 = 1 0
d = 1 , so C = 1 1 0 = 1 0
a = 2 3 4 − 3 4 + 9
a = 2 0 + 9
a = 1 + 9
a = 1 0
b = 1 0
d = b a
d = 1 0 1 0
d = 1
C = d a b
C = 1 1 0 0
C = 1 0
a = 10 ,, b = 10 ,, d =1 ,, c = ((a*b) ^ (1/2)) / d,, therefore.. (100 ^ (1/2)) / 1 = 10..
given a=b therfore a=2^0 + 9 = 10 a=10 on solving C=a therefore C=10
c=b/b/a c=1/1/a and a=2*0+9=1=9=10 so c=10
a=1+9=10=b d=a/b=a/a=1 C=a/1=10/1=10
a=10 b=a=10 d=1 c=10/1=10
where a=2^34-34 + 9. anything power zero is equal to 1.so 34-34=0. a=1+9=10; b=a:d=a/b. to find c=10/1=10.
a=2^(34-34)+9=1+9=10,b=10,d=10/10=1,c=10

We know that any number a to the power 0 is equal to 1 , i.e., a 0 = 1 .
Now, it is said that ---->
a = 2 3 4 − 3 4 + 9 and b = a
a = 2 0 + 9 and b = a
a = 1 + 9 = 1 0 and b = a = 1 0
Now, d = b a = 1 0 1 0 = 1
So, C = d a b = 1 1 0 × 1 0 = 1 0 0 = ± 1 0
But, since here only the positive answer is accepted as the correct answer, so the correct answer = 1 0
