Directions (1-5): What approximate value will come in place of the question mark (?) in the following equations? 1) 196.1 x 196.1 x 196.1 x 196.lx4.01 x4.001 x4.999 x 4.999 = 196.1* x4 x ?

Approximate the bases to their nearest integers to get (196 x 196 x 196 x 196) x (4 x 4 x 5 x 5) = 196 x 4 x ?. This simplifies to 196^4 x 400 = 196^4 x 4 x ?. Dividing both sides by 4, we get 196^4 x 100 = 196^4 x ?. Therefore, the question mark must be replaced by 100. The result is 100.
