Question

2la 19 •8la 7•25la 17=

Answer 1

2^19 •8^7•25^17= 2^19 •2^21•5^34 = 2^40*5^34 = 2^6*2^34*5^34=
 = 2^6*10^34 = 64*10^34,  adica 64 urmat de 34 de zero

Answer 2

8^7= (2^3)^7=2^21
25^17=(5^2)^17=5^34
2^19 x 2^21 x 5^34= 2^(19+21) x 5^34= 2^40 x 5^34= 2^34 x 2^6 x 5^34= 10^34 x 64= 64 urmat de 34 de zerouri
