Simplify the expression below:

9x6y².5x²y³

Calculate the product of numbers i.e. 9×6×5

If a term doesn't have an exponent, its implied exponent is 1

Multiply the terms with the same base by adding their exponents

Add the numbers in exponent

You can generalize the following rule:

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
