Solution :

To find the value that should replace the question mark (?), let us write down the given equation:
180×18×260×121=?3

Let the unknown value in place of the question mark be x. The equation becomes:
180×18×260×121=x3

Step 1: Simplify the fraction in the equation.
First, we can simplify 18060:
18060=3

Now, substitute this back into the expression:
3×18×2121=x3

Step 2: Simplify the remaining terms in the fraction.
We know that 3×2=6. So the numerator becomes:
6×18=108

Now, divide 108 by 12:
10812=9

Step 3: Substitute the simplified value back into the equation:
91=x3
8=x3

Step 4: Solve for x by taking the cube root of both sides:
x=83
x=2

Therefore, the value that will come in place of the question mark is 2.
