Use inductive reasoning to determine the units digit of the number 3 to the 58 power

We must find a pattern in the powers of 3:

So, as you can see, both and end with 1. So, we can generalize as follows:

Since , we can deduce that ends with 9.

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

f(x)=4
