convert the radical to rational exponent form.

-7Radical(a+b)

-7(a+b)^(1/2)

Thanks

To convert the radical to rational exponent form, we first need to understand the rule that relates radicals to rational exponents.

The rule states that for any positive real number n and any positive real number a, the nth root of a can be expressed as a^(1/n).

In this case, we have -7√(a+b). To convert this to rational exponent form, we can use the rule mentioned above.

So, we can rewrite -7√(a+b) as (-7(a+b)^(1/2)).

Therefore, the radical -7√(a+b) in rational exponent form is (-7(a+b)^(1/2)).
