3+5=8
Answer:
2/8
Step-by-step explanation:
probability = total number of items ÷2
=8÷2
=2/£
(3s^13)(9s^-5) is simply a matter of multiplication.
First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8
