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

Answer:

(a)

Step-by-step explanation:

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

$\frac{x}{y}$

= $\frac{3(15)}{5(10)}$

= $\frac{45}{50}$ = $\frac{9}{10}$ → (a)
