4) a²b+ 2a√/b+4
a√b +2 ​

Ответ:One way to simplify the expression 4a²b + 2a√/b + 4a√b + 2 is to factor out the common term 2a from the first three terms. This gives us:

2a(2ab + √/b + 2√b) + 2

Next, we can use the identity √/b = √b/b to rewrite the second term inside the parentheses as:

2a(2ab + √b/b + 2√b) + 2

Then, we can combine the fractions with a common denominator of b and simplify:

2a((2ab² + b√b + 2b√b)/b) + 2

2a((2ab² + 3b√b)/b) + 2

Finally, we can divide by b and get the simplified expression:

2a(2ab + 3√b) + 2
