How t solve polynomials????? HELPPPP EXAM TMRW!!!!
Alecsey [184]

Answer:

B) 1296 D) 729

Step-by-step explanation:

It's pretty straight forward, just put the values into your calculator. The question is asking to evaluate instead of simplifying, so this works. If you don't have a calculator, here are some tricks. Do them step by step in your head slowly if you have to, for fractions do them alone, and then divide them. Also in D, don't let the second value of (3)3)0 scare you, any exponent with a 0 in it is automatically 1! Hope I could help.
