Question

10 X^-1×y^-10 • 0,05 X^2y^-10

Answer 1

Я написала два варианта, а какой выберешь ты, сам(-а) решай:

1)(10/x×y^10)×(0,05x²/y^10)=(0,5x/y^20).
2)10×0,05×x^(-1+2)×y^(-10+(-10))=0,5×x^1×y^(-20)=0,5x/y^20.

Answer 2

To simplify the expression, let's combine the terms with the same base. Remember that when you multiply two terms with the same base, you can add their exponents. The expression is:

10 * X^(-1) * y^(-10) * 0.05 * X^2 * y^(-10)

Now, let's simplify the X and y terms separately:

X^(-1) * X^2 = X^(2 - 1) = X^1 = X y^(-10) * y^(-10) = y^(-10 + (-10)) = y^(-20)

After simplification, the expression becomes:

10 * 0.05 * X * y^(-20)

Now, multiply the constants:

10 * 0.05 = 0.5

The final simplified expression is:

0.5 * X * y^(-20)

Or equivalently:

0.5XY^(-20)
