Work out the following sums
1. Represent the following as indicated
a. 0.000000000085( Standard form)
b. 1.0007 x 10^11 ( Usual form)
2. verify the following
a. If p = -3/2 q = 4/5 then prove that p x q = q x p
b. With the same values of p and q prove that p+q = q+p
3. Find the multiplicative inverse of the following:
a. -4/5
b. 2/3
4. Find the additive inverse of the following:
a. -6/3
b. 7/9
5. Sum of 2 numbers is 3/5. If one of them is -2/7, Find the other.
6. If x= 4/9 y= -7/12 and z = -2/3 then verify that x-(y-z) is not equal to (x-y)-z
7. With the same values of x , y and z show that X*(Y+Z)= X*Y + X*Z
