Answer:

n = 4 and n = -10

Explanation:

l n + 3 l + 8 = 15

l n + 3 l = 7

Two solutions

n + 3 = 7

n = 4

and

n + 3 = -7 (since we are dealing with absolute numbers, one side has to be multiplied by -1)

n = -10

Find the indicated real nth root(s) of a. n=3, a=729

marissa [1.9K]

Answer:

Step-by-step explanation:

n=3, a=729

For any odd integer, n ; a will have only one real nth root which will be a positive integer.

Similarly, for any integer, n, that is > 1 ; related by the expression ;

p^n = a ; the nth root of a = p

Therefore,

If n = 3 ; a = 729

p^3 = 729

To obtain the value of p ; take the cube of both sides

(p^3)*1/3 = 729^1/3

p = 9

Hence, the real nth root of 729 is +9 when n = 3
