Can somebody PLEASE help me with this :) ??

Given the function f(x) = log base 4(x+8) , find the value of f^-1(2)

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

1. which of the following algebraic equations is equivalent to ? x^n = a a^n = x a^x = n x^a = n 2. 16^1/4= 1/2 2 4 3. (-36)^1/2= -6 1/6 no real number 4. 8^2/3= 4 8 16√2 )^5/2= 7,776 1/7,776 no real number 6. m ^ the square root of a^2m simplified is: 7. the square root of 3^3 times the square root of 2 simplified and in radical form is:
