You would have to make common denominators
consider a/b,c/d in Q
then a/b - c/d = ad/db - cb/bd = (ad-cb)/db for all a,b,c,d in R, exclude b,d=0
i.e. 1/2 - 1/4
=4/8 - 2/8 =(4-2)/8=2/8 =1/4
Answer: 3/2
Step-by-step explanation: it’s just the number with the variable
We need to convert given value 465^8 as the base 5 number.
Let us assume x is the exponent of 5 when we take base 5.
We can setup an equation now.
5^x=465^8
Taking ln on both sides, we get





On simplifying, we get

Therefore,
.
It 730 because when you round to the nearest ten its 740
So 10 more will make it 740
