Answer:
x = -7 or x = 1
Step-by-step explanation:
Given expression:
(x + 3)² = -16
Problem;
Solve for x;
Solution:
To solve for x; we use the factorization method;
Take -16 to the left of the equation;
(x + 3)² = -16
(x + 3)² + 16 = 0
(x+ 3)² + 4² = 0
if x² + y² = (x + y)(x - y)
So;
(x + 3 + 4) (x + 3 - 4) = 0
(x + 7)(x - 1) = 0
x + 7 = 0 or x - 1 = 0
x = -7 or x = 1

2) x times the seventh root of x cubed
Step-by-step explanation:
![\displaystyle\sqrt[7]{x^5}\cdot\sqrt[7]{x^5}=\sqrt[7]{x^{5+5}}\\\\=\sqrt[7]{x^{7+3}}=\sqrt[7]{x^7}\cdot\sqrt[7]{x^3}\\\\=x\sqrt[7]{x^3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csqrt%5B7%5D%7Bx%5E5%7D%5Ccdot%5Csqrt%5B7%5D%7Bx%5E5%7D%3D%5Csqrt%5B7%5D%7Bx%5E%7B5%2B5%7D%7D%5C%5C%5C%5C%3D%5Csqrt%5B7%5D%7Bx%5E%7B7%2B3%7D%7D%3D%5Csqrt%5B7%5D%7Bx%5E7%7D%5Ccdot%5Csqrt%5B7%5D%7Bx%5E3%7D%5C%5C%5C%5C%3Dx%5Csqrt%5B7%5D%7Bx%5E3%7D)
