Step-by-step explanation:
2n + 5 = 27
2 * 11 + 5 = 27
22 + 5 = 27
27 = 27
11 is the solution to this equation.
A(n)=A(n-1)+17 with A(1)=3
What is inside the parentheses can also be written as a subscript.
Hope this helps!
The exponent 4 needs to be applied to both 3 and x, so we would have:
3 * 3 * 3 * 3 * x^4.
9 * 9 * x^4.
81x^4
