Plug 3 into the k in the first equation. Multiply by 3 to cancel out the fraction. This leaves you with x-1=9. Add 1 to both sides and you get x=10.
Answer:
56 as a product of primes using index notation is: 
Step-by-step explanation:
We need to write 56 as a product of primes.
Prime Numbers:
<em>Numbers that are divisible by 1 or itself.</em>
Now, writing 56 as product of primes
56 = 2 x 2 x 2 x 7
Now, Use index notation when giving your answer.
Index Notation:
<em>Express elements in power form i.e. if we have 2 x 2 we can write it as 2^2</em>
So, answer will be:


So, 56 as a product of primes using index notation is:
