X2 + -4 = 0
Reorder the terms:
-4 + X2 = 0
Solving
-4 + X2 = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X2 = 0 + 4
Combine like terms: -4 + 4 = 0
0 + X2 = 0 + 4
X2 = 0 + 4
Combine like terms: 0 + 4 = 4
X2 = 4
Simplifying
X2 = 4
Take the square root of each side:
X = {-2, 2}</span>
I think we must use two numbers which have two digits and one of them must be one digited number.If we try it we can say our numbers are xy,ab and c.
xy + ab + c = 50
10x+y+10a+b+c = 50
10(x+a) + y+b+c = 50
Think about y+b+c. Maximum it can be 5+4+3 = 12 but it can't because there is a number which is multiple of 10.So it can be 10 maximum and x+a must be 4.
We can only use 1+3. 40 + y+b+c = 50 , y+b+c = 10. And other numbers are 2+4+5 = 11. 10 doesn't equal to 11 and it says there isn't any solution for this problem :)
Answer:
<u>The correct answer is C. 21x³y</u>
Step-by-step explanation:
Let's simplify the product, this way:
(49x²y)^1/2 * (27x⁶y^3/2)^1/3
Let's recall that x^1/2 = √x and x^1/3 = ∛x
√(49x²y) * ∛(27x⁶y^3/2)
7x √y * 3x² √y
Let's recall that √y * √y = √y² = y
21x³y
<u>The correct answer is C. 21x³y</u>
