Consider the given two expressions and
We have multiply both expressions,
To multiply two terms first multiply constant numbers that is 6 × 2 = 12
For x , y and z apply property of exponent,
Then power of x together will be,
Similarly for y powers,
Since first term do not have any expression for z so it will remain same.
Thus, the given expression on multiplying become,
is

From the picture :
The nine chips are : 1, 2, 3, 4, 5, 6, 7, 8, 9
Even chips = 2, 4, 6, 8
Probability = number of required outcomes / (number of total possible outcomes)
Probability of drawing a chip with an even number :
P(even number) = number of even chips / total number of chips
P(even number) = 4 / 9
Answer:
3 machine
Step-by-step explanation:
It is given that 6 machine each working at the same rate can complete the work in 12 days
We the has to complete in 8 days
Let we need x extra machine to complete the work in 8 days
So total number of machines =x+6
Now according to man work day equation
x=3 machine
