What is the value of y in this simplified expression?
k + m 10

y=5

x=7

Step-by-step explanation:

When given an expression in the form a⁻ᵇ the expression is the same as 1/aᵇ where  a and b are integers.

Solving the question by giving the equivalents of the expression:

Therefore (-j)⁻⁷ is the same as 1/j⁷

The value of x=7

k⁻⁵+m⁻¹⁰=1/k⁵+1/m¹⁰

Therefore the value of y is 5.

Question 1:

For this case we have that by definition of properties of powers it is fulfilled that:

So, if we have the following expression:

We can rewrite it as:

So we have to:

Question 2:

For this case we have that by definition of properties of powers it is fulfilled that:

If we have the following expression:

We can rewrite it as:

So we have
