Simplify: (-(7)/(9))times(3)/(8)times(-(4)/(7))

Simplify : ( 16 xx 10 ^(4) xx 3^(3))/( 6^(5) xx 5^(6))

Simplify (8^(3a)xx2^(5)xx2^(2a))/(4xx2^(11a)xx2^(-2a))

Simplify : a. 15^(7)-:5^(3) b. ((5^(4))^(3)xx2^(12))/(3^(12)) c. ((4^(3))^(2)xx5^(6))/(10^(6)) d. (2xx3^(4)xx2^(5))/(9xx4^(2)) e. (2^(2)xx3^(4)xx16)/(3^(2)xx32) f. (4^(5)xxa^(8)xxb^(16))/(4^(4)xxa^(7)xxb^(4))

Show that (4)/(7)times((-2)/(8)+(3)/(4))=(4)/(7)times(-2)/(8)+(4)/(7)times(3)/(4)

Simplify : (4xx10^(-2))-(2.5xx10^(-3))

Simplify : ((8)/(27))^(-1//3)xx((25)/(4))^(1//2)xx((4)/(9))^(0)+((125)/(64))^(1//3)
