If I read your post properly, the two fractions are -14/10 and -12/b.
The LCD is found by finding prime factors of each term, then collecting the ones that appear the most.
10 = 2 x 5
b = b
2 x 5 x b = 10b
The sign in the exponent: positive->increases, negative->decreases. Think that a negative sign implies 1/exponential and you'll clearly see the reason.
Answer:
Step-by-step explanation:
To begin simplifying this, we can first divide the coefficients, giving us:
We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:
Now, simplifying this gets:
Answer:
x=8
Step-by-step explanation:
Step 1: Subtract 6 from both sides.
4x+6−6=38−6
4x=32
Step 2: Divide both sides by 4.
4x
4
=
32
4
x=8
Answer:
2-11i
Step-by-step explanation:
-2-5i - (-4+6i)
Distribute the minus sign
-2-5i +4 -6i
Combine the real parts
-2+4 = 2
Combine the imaginary parts
-5i-6i = -11i
the complex number is
2-11i
