Answer:
2a) 125
2b) 81
Step-by-step explanation:
For 2a:
Whenever one is multiplying there is a two exponents but one is out of the parentheses, you multiply the exponents
So I multiplied the 3 and 1 exponents to get 3 which I then multiplied the new exponent (3) with the base (5) to get 125
For 2b:
Whenever two exponents are multiplied with no parentheses meaning it is just an equation, we add the exponents together. Note, when the exponent is 0, the answer will always be 1.
3^0= 1
1 x 3^4= 81
