Question

Exponents and powers .pls answer

Answer 1

Answer:The answer is option (a)

Step-by-step explanation: For this question, since all 3 terms have the same power, you compare the bases and ignore the powers. So you have 3/5 × 15/10 = x/y. That is 45/50 = x/y. Reducing to the lowest terms 9/10 = x/y. I hope that helped.

Answer 2

(a)

Explanation:

Since all ratios are raised to the power of 4, then

`(x)/(y)`

=
`(3(15))/(5(10))`

=
`(45)/(50)` =
`(9)/(10)` → (a)
