Question

just give me a BASIC IDEA how to solve. ....

only idea..

Answer 1

hello...

hint / idea -

Just take log..

then generate 10 both sides...

you will get answer as (c)
i.e 6603

thank you....

☺

Answer 2

Answer:

Option - C.

Explanation:

Let x = 2000^2000.

Apply log on both sides, we get

= > log x(base 10) = log 2000^2000(base 10)

= > log x(base 10) = 2000 log2000(base 10)

= > log x = 2000 * log 2 * 1000

= > log x = 2000(log 2 + log 1000)

= > log x = 2000(0.3010 + 3)

= > log x = 6602.


Therefore the number of digits = logx + 1

                                                     = 6602 + 1

                                                     = 6603.


Hope this helps!
