10 cuz it’s a 2 € 10 and it’s 10
I believe you have to use power rules for these so for the numerator (x^5yz^4)^3 the power outside of the bracket will multiply with the powers inside the bracket in order to simplify this part so the numerator of the fraction would be x^15y^3z^12 (because 5x3=15, 1x3=3, 4x3=12)
Next simplify the fraction this is done by subtracting the powers so x^15y^3z^12/x^3yz =x^12y^2z^11 (because any singular letter term ie y can also be seen as y^1, using this 15-3=12, 3-1=2, 12-1=11) this is your final answer so a=12 b=2 and c=11
4x + 7y = 1 ⇒ 12x + 21y = 3
3x + 10y = 15 ⇒ <u>12x + 40y = 60</u>
<u>-19y</u> = <u>-57</u>
-19 -19
y = 3
4x + 7(3) = 1
4x + 21 = 1
<u> - 21 - 21</u>
<u>4x</u> = <u>-20</u>
4 4
x = -5
(x, y) = (-5, 3)
Answer:
The answer in the procedure
Step-by-step explanation:
we have



we know that
The formula to solve a quadratic equation of the form
is equal to
