`(-8)^3xx(-9)^3-:6^5`

Fill in the blanks i (-6)xx(........) = 6 ii (-18)xx(.......) = (-18) iii (-8) xx (-9) = (-9) xx (...) iv 7 xx (-3) = (-3) xx (…) v {(-5)x3}x(-6) = (...)xx{3xx(-6)} vi (-5)x(...)=0

Solve :- (-11) xx (-9) xx (-5) xx (-6) xx (-3) = ?

Find each of the following products: i 3xx4xx(-5) ii 2xx(-5)xx(-6) iii (-5)xx(-8)xx(-3) iv (-6)xx6xx(-10) v 7xx(-8)xx3 vi (-7)xx(-3)xx4

( (5)/(6)-:(6)/(7)times(6)/(7)-(8)/(9)-:1(3)/(5)+(3)/(4)times3(1)/(3)

The product (-9)xx(-5)xx(-6)xx(-3) is positive whereas the product (-9)xx(-5)xx6xx(-3) is negative. Why?

The product (-9)xx(-5)xx(-6)xx(-3) is positive where as the product (-9)xx(-5)xx6xx(-3) is negative .Why ?
