If the square root of a + 1 and the square root of 2b-6 are opposite numbers, then the cube root of a + B is? It's very urgent, and it's analytical. Well intentioned, it's for you,

Arithmetic square root non negative numbers are opposite to each other, numbers can only be 0 and 0
A + 1 = 0, a = - 1, 2b-6 = 0, B = 3, the cube root of a + B is the cube root of 2
