We have been given an expression . We are asked to find the value of A when rewrite our given expression as
.
To solve our given problem, we will use exponent properties.
Using exponent property , we can rewrite our given expression as:
Now, we will compare our expression with .
Upon comparing with
, we can see that
.
Therefore, the value of A is .
We can further simplify as:
I suppose you want to know such number. Since we have a two digit number consisting of two consecutive integers, the only possible numbers are:
Since we sorted all the cases out, we simply have to check which one satisfies the requirement. For each number, we'll write four times the the sum of its digits, and add 6, hoping to get the original number.
So, the answer is 34.
