Question

The number of consecutive zeros in 23×34×54×7 , is

Answer 1

Given: correct term is 2*3 x 3*4x 5*4 x7

To find : the number of consecutive zeros in above term

Step-by-step explanation:

* to find consecutive zeros, we have to make multiplication with ending with zero .

*so we can say that multiplication of 2 and 5 always give zero , however the no. of zeros always equal to the number of 2and 5 in the expression , which is minimum .

so, 2*3x3*4x5*4x 7

2*3 x 3*4x 5*3 x 5 x7

........ spilliting 5

(2x 5) *3 x 3*4 x 5 x7

......... multipliying 2and 5

( 10 ) *3 x 3 *4 x 5 x 7

3* 4 x 5 x 7 x 1000

.

so we get 3 zeros

Answer : So, in the given natural number there are three zeros
