Question

a=2^37×8^13:(4^3)^7×25^17
b=2^20+2^19+2^16
Sa se afle catul ptr a:b.
Multumesc!

Answer 1

a =2^37 * (2^3)^13 : (2^2)^21 * 25^17

a= 2^37 * 2^39 : 2^42 * 25^17

a= 2^(37+39-42) * 25^17

a=2^34 * 25^17

b=2^16(2^4+2^3+1)

b=2^16*(16+8+1)

b=2^16*25

a:b= (2^34 * 25^17) : (2^16 * 25) = 2^(34-16) * 25^(17-1) = 2^18 * 25^16
