Question

(a+5)*6a(1-5a)/(1-5a)*(a+1)*a*(a+5)

Answer 1

Ответ должен быть 3 а

Answer 2

Сокращаем (1-5а) с тем же числом знаменателе . и (а+5) . остаётся:
6а/(а+1)×а = 6а/2а . сокращаем на 2 :
3а/а = 4

Answer 3

Let's simplify the given expression step by step:

1. Combine like terms: (a + 5) and (a + 1)
2. Factor out common terms: 6a, (1 - 5a), a, (a + 5)

Here's the simplified expression:

(a + 5) * 6a * (1 - 5a) / (1 - 5a) * (a + 1) * a * (a + 5)

Step 1: Combine like terms = 6a * (a + 5) * (1 - 5a) / (1 - 5a) * (a + 1) * a * (a + 5)

Step 2: Factor out common terms = 6a * a * (a + 5) * (1 - 5a) / (1 - 5a) * (a + 1) * (a + 5)

Step 3: Cancel out the common term (1 - 5a) in the numerator and denominator = 6a * a * (a + 5) * (a + 1) * (a + 5)

Step 4: Rearrange the expression = 6a * a * a * (a + 5) * (a + 5) * (a + 1)

Step 5: Simplify = 6a^3 * (a + 5)^2 * (a + 1)

So, the simplified expression is 6a^3 * (a + 5)^2 * (a + 1).
