(ii) `(7/8)^(-1/4) xx (7/8)^(1/2) xx (7/8)^(3/2)`

(2/3)^(-2) xx (3/4)^(-3) xx ((-7)/8)^o

Name the property of multiplication shown by each of the following statements: (i) (-12)/(5) xx (3)/(4)=(3)/(4)xx (-12)/(5) (ii) (-8)/(15) xx 1=(-8)/(15) (iii) ((-2)/(3) xx (7)/(8)) xx (-5)/(7) = (-2)/(3) xx ((7)/(8) xx (-5)/(7)) (iv) (-2)/(3) xx 0=0 (v) (2)/(5) xx ((-4)/(5) +(-3)/(10)) = ((2)/(5) xx (-4)/(5)) +((2)/(5)xx (-3)/(10))

Simplify: (6/7)^3 xx (7/6)^2 xx ((-6)/8)^3

The value of ((7)/(8) div 5(1)/(4) xx 7(1)/(5) - (3)/(20) " of " (2)/(3)) div (1)/(2) + ((3)/(5) xx 7(1)/(2) + (2)/(3) div (8)/(15)) is equal to 7+k , where k =

7/5 xx((-3)/8) + 3/4 xx 7/5

Simplify (i) 3^((1)/(4)) xx 5^((1)/(4)) (ii) 2^((5)/(8)) xx 3^((5)/(8)) (iii) 6^((1)/(2)) xx 7^((1)/(2))

(49)^(2) xx (7)^(8) div (343)^(3) = (7)^(?)

{(99-1) // 7^(2)} xx 2+ 8 = ?
