-7�ã(a+b)

convert the radical to rational exponent form.

-7Radical(a+b)

what is the rational exponent form of ratical b to the 7th power?

To solve the expression -7(a+b), you can simplify it by applying the distributive property.

The distributive property states that when you have a number outside of parentheses multiplied by a sum inside the parentheses, you can distribute the multiplication to each term inside the parentheses.

In this case, -7 is the number outside the parentheses, and (a+b) is the sum inside the parentheses. To distribute -7, you need to multiply it by both a and b separately.

So, the simplified expression becomes:

-7(a+b) = -7(a) - 7(b)

Now, you have two separate terms: -7(a) and -7(b).

To simplify further, you can multiply -7 with a and b respectively:

-7(a) = -7a
-7(b) = -7b

Therefore, the final simplified expression is:

-7(a+b) = -7a - 7b
