Question

Сократить дробь:у^+у/у^

Answer 1

Условие задано странно и читается по-разному:
1)  $\frac{y^{y}}{y} = \frac{y^{y}}{y^{1}} = y^{y - 1}$

Если    " у^ "   -   это " у² "  ..
2)  $y^{2} + \frac{y}{y^2} = y^2 + \frac{1}{y}$

3)  $\frac{y^2 + y}{y^2} = \frac{y(y+1)}{y*y} = \frac{y+1}{y} = \frac{y}{y}+ \frac{1}{y} =1 + \frac{1}{y}$

Answer 3

I assume you meant to write the expression as:

(u^2 + u) / u^1

To simplify this expression, remember that when you have the same base raised to different powers in the numerator and denominator, you can subtract the exponents. In this case, the base is "u."

(u^2 + u) / u^1 = u^(2-1) + u^(1-1) = u^1 + u^0

Now, anything raised to the power of 0 is equal to 1. Therefore, the simplified expression is:

u^1 + 1 = u + 1

So, the simplified form of the expression is "u + 1."
