Question 159(ii)

Using law of exponents, $a^m\times a^n=a^{m+n}$ [$\because$ a is non-zero integer]

Answer 1

Using law of exponents, $a^m\times a^n=a^{m+n}$ [$\because$ a is non-zero integer]
Repeator machine can do the work is equal to ${100}^2\times {100}^{10}$.
So, $\times {100}^{12}$ single machine can do the same work.
