Find the greatest common factor of 9y^4 and 7y^3

63 y4 is the common factor

The greatest common factor of 9y^4 and 7y^3 is

Solution:

We have to find the greatest common factor of

G.C.F is the largest factor that all terms have in common.

Let us first find the factors of

 --- eqn 1

 --- eqn 2

Here 9 and 7 are co-prime numbers, Co-prime are the numbers which only have 1 as the common factor

From Equation (1) and (2)

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
