Question

20^-12*5^13/4^-14
Помогите решить пожалуйста.

Answer 1

$frac{ {20}^{ - 12} times {5}^{13} }{ {4}^{ - 14} } = frac{ {4}^{ - 12} times {5}^{ - 12} times {5}^{13} }{ {4}^{ - 14} } = {4}^{ - 12 - ( - 14)} times {5}^{ - 12 + 13} = {4}^{2} times 5 = 16 times 5 = 80$

Answer 2

20^(-12)*5^13/4^(-14)=

4^(-12)*5^(-12)*5^(13)/4^(-12)*4^(-2)=

5/4^(-2)=5*16=80
