" 7."((-13)/(5)ab^(2)c)times((7)/(3)a^(2)bc^(2))

Find the products ((-13)/(5)ab^(2)c)xx((7)/(3)a^(2)bc^(2))

Multiply: (i) 6ab by 4b (ii) 5ab^(2)c^(3) by 7a^(2)bc (iii) -6x^(2)yz by (2)/(3)xy^(3)z^(2) (iv) (-8)/(5)a^(2)bc^(3) by (-3)/(4)ab^(2)c

(2a^(2)b)xx(-5ab^(2)c)xx(-6bc^(2))

(1(1)/(13)times2(3)/(5))-:(7(1)/(2)times3(1)/(10))-:(28)/(279)

((-2)/3)^(2//7)xx((-2)/3)^(5//7) =

((13)^(3)+7^(3))/((13)^(2)+7^(2)-?)=20

[((-2)/(-3))times(1)/(5)]times((-2)/(7))=((-2)/(-3))times[(1)/(5)times((-2)/(7))]

2 3/5-:5/7=\ (a) (13)/7 (b) (13)/(25) (c) (91)/(25) (d) (25)/(91)

((5^(-1)xx7^(2))/(5^(2)xx7^(-4)))^((7)/(2))xx((5^(-2)xx7^(3))/(5^(3)xx7^(-5)))^(-(5)/(2))

Simplify ((7)/(2)-:(5)/(2)xx(3)/(2))/((7)/(2)-:(5)/(2)" of "(3)/(2))-:(15)/(14)
