Question

А) 1+✓a/✓a б) y+b✓y/b✓y в) x-✓ax/a✓x

Answer 1

Объяснение:

а) ✓а/✓а = 1

1+1=2

б) b✓y/b✓y=1

y+1

в) ✓ах/а✓х=а^(1/2-1) * х^(1-1/2)= а^(-1/2) * х^1/2= ✓х/✓а

х-✓х/✓а

Answer 2

Let's simplify each expression step by step:

a) Simplifying 1 + √a / √a: We can simplify this expression by rationalizing the denominator. √a / √a is equivalent to (√a * √a) / (√a * √a) = a / a = 1 Therefore, the expression simplifies to 1 + 1 = 2.

b) Simplifying y + b√y / b√y: Similar to the previous expression, we can rationalize the denominator. b√y / b√y is equivalent to (b√y * b√y) / (b√y * b√y) = y / y = 1 Therefore, the expression simplifies to y + 1.

c) Simplifying x - √ax / a√x: Here, we can also rationalize the denominator. √ax / a√x can be written as (√ax * a√x) / (a√x * a√x) = ax / ax = 1 Therefore, the expression simplifies to x - 1.

To summarize: a) 1 + √a / √a simplifies to 2. b) y + b√y / b√y simplifies to y + 1. c) x - √ax / a√x simplifies to x - 1.
