Step-by-step explanation:
The given Question can be expressed as,
2^30
= (2^2)^15
= 4^15
= (4^3)^5
= 64^5
= 64 × 64 × 64 × 64 × 64
= 64² × 64² × 64
Now, 64² will have 4 digits
So, 64² × 64² will have 8 digits
Then, 64² × 64² × 64 will have 10 digits.
Reason is that, the number of digits you multiply with, that many digits the number has.
I solved this on a paper
64² × 64² × 64
= 4096 × 4096 × 64
= 16777216 × 64
= 1073741824
It has 10 digits
