Answer:
"principal root"
Step-by-step explanation:
The positive (even or odd) root of a positive real number is called its <em>principal root</em>.
__
When an odd root is taken of a negative real number, the negative real root is the principal root. That is -2 is the principal cube root of -8.
Answer:


Step-by-step explanation:
Let x and y are the two positive real numbers
product of two numbers is 21


The sum of the two numbers is f(x) =x+y
Replace y with 21/x

we need to find smallest possible sum , so we take derivative using power rule

when sum is minimum then the derivative is equal to 0


multiply both sides by x^2


Take square root on both sides

Answer:
y = 4x - 3
Explanation:
4x – y + 6 = 9 Subtract 6 from each side
4x – y = 3 Subtract 4x rom each side
-y = -4x + 3 Multiply each side by -1
y = 4x - 3
