Answer:
3 a^(-2)
3 / a^2
Step-by-step explanation:
(3a) (a^-3)
Multiply
3 a^1 * a^-3
Since we are multiplying, we add the exponents
3 a^ ( 1-3)
3 a^(-2)
If you are not supposed to leave a negative exponent
x^-b = 1 / x^b
3 / a^2
You first have to see if they have the same common denominators. If they do then the operation as in addition you add the numerator and denominator together and she if it can be reduced into a smaller number
For a, x = 6 (3+6=9) and for b, y=5 (2x5=10)
Answer:
10.5
Step-by-step explanation:
sin29
k
=
sin124
18
Plug in. Opposite sides go together.
k=\frac{18\sin 29}{\sin 124} \approx 10.526 \approx 10.5
k=
sin124
18sin29
≈10.526≈10.5
4/26 can be simplified by 2. So, this is not the answer.
8/21 cannot be simplified. So, it is one of the answers.
6/19 cannot be simplified. So, it is one of the answers.
9/10 cannot be simplified. So, it is one of the answers.
10/22 can be simplified by 2. So, this is not the answer.
So, the fractions in simplest forms are 8/21, 6/19, and 9/10.
