Question

49⁵·7¹²/343⁷=
(4/7)⁶·(1 3/4)⁴=

Answer 1

1) 49^5 • 7^12 = 7^10 • 7^12 = 7^22
2) 343^7 = ( 7^3 )^7 = 7^21
3) 7^22 : 7^21 = 7^1 = 7
Ответ 7
••••••••••
1) ( 1 3/4 ) = ( 7/4 )^4
2) ( 4/7 )^6 = ( 7/4 )^-6
3) ( 7/4 )^-6 • ( 7/4 )^4 = ( 7/4 )^-2 = ( 4/7 )^2 = 16/49
Ответ 16/49

Answer 2

1)49^5*7^12/343^7=7^10*7^12/7^21=7^22/7^21=7 2)(4/7)^6*(1 3/4)^4=(4/7)^6*(7/4)^4=(4^6*7^4)/(7^6*4^4)=4^2/7^2=16/49
