Pick up the positive integers form the following numbers : (A) `0`
(B) `(-3)xx(-3)`
(C) `3xx(-3)`
(D) `3xx3`

(-3)xx(-3)xx(-3)xx(-3)=

9xx(-1/3)xx(-3)xx(-1/9)= 1 (b) -1 -3 (d) 3

Which of the following is not zero? (a) 0xx0 (b) 0/3 (c) (7-7)/3 (d) 9+0

9xx(-1/3)xx(-3)xx(-1/9)= (a) 1 (b) -1 (c) -3 (d) 3

Express each of the following in exponential form: (-4)xx(-4)xx(-4)xx(-4)xx(-4)xx(-4) (ii) 3/5xx3/5xx3/5xx3/5

Find the number from each of the following expanded forms : , (a) 8 xx 10^4 + 6 xx 10^3 + 0 xx 10^2 + 4 xx 10^1 + 5 xx 10^0 , (b) 4 xx 10^5 + 5 xx 10^3 + 3 xx 10^2 + 2 xx 10^0 , (c) 3 xx 10^4 + 7 xx 10^2 + 5 xx 10^0

Find the number from each of the following expanded forms :(a) 8xx10^(4)+6xx10^(3)+0xx10^(2)+4xx10^(1)+5xx10^(0) (b) 4xx10^(5)+5xx10^(3)+3xx10^(2)+2xx10^(0)(c)3xx10^(4)+7xx10^(2)+5xx10^(0)

Simplify and express each of the following in exponential form: (2^(3)xx3^(4)xx4)/(3xx32)

Property 3 (Associativity): the multiplication of integers is associativie.for any three integers abc we have a xx(b xx c)=(a xx b)xx c
