1. Convert the root into a fractional power. A root of a number is the number to the power of the inverse of that root number. When an exponent is outside a brackets you multiply the exponents.
2.Square root (x+4) -3=1
square root (x+4)=4
(x+4)=(4^2)
x+4=16
x=12
3. f(g(x))=(2x^2+5)^2+2x^2+5+2
f(g(x))=4x^4+20x^2+25+2x^2+7
f(g(x))=4x^4+22x^2+32
4.
A. The descending order of this expression is 7a^3+5a^2b-13ab-4b.
B. This is a polynomial.
C. This is a 3rd degree polynomial.
