Alright, so I'll give you some general guidelines and challenge you to solve this on your own!

If we have a number x , a number z, and a number y, then 
x^{y^{z}} = x^{y * z}
For example, 
2^{3^{4}} = 2^{3*4}=2^{12}

Next, x^{y} * x^{z}=x^{y+z} . For example, 2^{3}*2^{4}=2^{3+4}=2^{7}

Lastly, \frac{x^{y}}{x^{z}} =x^{y-z} . For example, \frac{2^{3}}{2^{4}} =2^{3-4}=2^{-1} . In this situation, note that a negative exponent means we have 1 over the actual positive exponent. For example, 2^{-1}= \frac{1}{2^{1}} =1/2

Please remember PEMDAS as well - 
P - Parenthesis
E- Exponents
M/D - Multiplication/Division
A/S - Addition/Subtraction
Go from top to bottom


Good luck, and feel free to ask any questions!

How to simplify 9+5(4x+4)
RoseWind [281]
Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29
