50 = 25 (2) = (5^2) 2\\\\22 = 11 (2) \Rightarrow\\3\sqrt{50}  \cdot \sqrt{22}  = 3\sqrt{5^2 \cdot 2}  \cdot \sqrt{11 \cdot 2} = 15 \sqrt{2}\cdot \sqrt{2}  \cdot \sqrt{11} = 15(2) \cdot \sqrt{11} = 30 \sqrt{11}

5x² + 3y when x =-2 and y = 10​
Vera_Pavlovna [14]

Answer:

50

Step-by-step explanation:

When a number is next to a variable, such as 5x, this means you will multiply them(five times x). With x being -2, we will multiply -2 x -2 = 4. the exponent tells you how many times to multiply a number by itself. If the exponent was 5, we would multiply 2 by itself 5 times to get 10. Since we got 4 for our answer, we will multiply that by since it was an exponent and we multiply it. 4 x 5 = 20. Since we know that we multiply numbers next to variables, we will multiply 3y or 3(10). 3 x 10 = 30. Add this to 20 to get your answer. 20 + 30 = 50.

Hope this helps :)
