Answer:
how do i know you are not point scammer?????
Step-by-step explanation:
We will start with 3 x 7 = 21
Multiply the values under the root
Square root 36 = 6 and square root y^4 = y^2
Then multiply 21 by 6y^2
The answer is D
Step-by-step explanation:
Answer:
The values of x and y are x = -3 and y = -2
Step-by-step explanation:
In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal
Let us use this rule to solve the question
∵ -21 + 5yi = 7x - 10i
∴ The real parts are -21 and 7x
∴ The imaginary parts are 5y and -10
∵ The real parts are equal
∴ 7x = -21
→ Divide both sides by 7
∴ =
∴ x = -3
∵ The imaginary parts are equal
∴ 5y = -10
→ Divide both sides by 5
∴ =
∴ y = -2
∴ The values of x and y are x = -3 and y = -2
