Question

how many consecutive zeros are there at the end of 2^3 × 3^4 ×5^4×7​

Answer 1

Answer:

Answer is 3

Step-by-step explanation:

we can make zero only by multiplying 2 and 5, like

2*5=10

2*2*5=20

so we can conclude here multiplication of 2 and 5 always brings 0, however no of zeros always equal to the no of 2 and 5 in the expression, whichever is minimum.

so here comes at the question, we have to find consecutive no. of zeros, for this we have to find the find the no. of 2 and 5 in the expression and answer will be minimum one.

so in the given expression,

no. of 2=3 and no. of 5 = 4

hence your answer is 3, we can make 3 consecutive zeros by solving this expression.
