Step-by-step explanation:

For the first question, divide the fractions. Hint: when you divide variables with exponents, subtract exponents from one another.

The math comes out to b.

2. Fill in the variables with the numbers listed. So, the equation is now:

25(2)^2(1)^4 / 5(2)(1)^2 = 100/10 = 10

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
