Answer:
Missing Number: 70,000,000
Answer: A, B, C, and E
Step-by-step explanation:
If both sides are real numbers, then the product will be a real number.
If in at least one of the sides we have a complex number, then the product will be real if:
The other number is zero.
The other number is the conjugate of the first.
This is when:
Suppose we have a number:
z = a + b*i
The conjugate will be:
w = a - b*i
And the product between them is:
(a + b*i)*(a - b*i) = a^2 + a*b*i - a*b*i + b^2 = a^2 + b^2
Then the options that will have a real answer are:
A. (4+5i)(4-5i) = 4^2 + 5^2 = 16 + 25 = 41
B. (4 + 91)*(41 - 9) = 3040
C. (3 + 2*i)*(3 -2*i) = 3^2 + 2^2 = 9 + 4 = 13
E. (312 + 7i)*(312 - 7i) = 312^2 + 7^2 = 97,393
1) additive inverse property is when an integer is added to its opposite integer (ex: -3 + 3)
2. Sorry I didn’t learn signed numbers yet :(((
3. Commutative property is when you change the order of numbers in the expression but associative property is when you are regrouping numbers in the expression.
4. Absolute value is the distance between an integer and 0. And yes you can solve distance problems and grid problems using absolute value.
Answer:
(1,-3)
Step-by-step explanation:
Answer:
n=1, m=3, and p=-4
Step-by-step explanation:
Take the fourth root of both sides
so x^n*y^m*z^p=x*y^3*z^-4;
notice z has a negative exponent because it was in the denominator
therefore, n=1, m=3, and p=-4
