Answer:
31/35x^7
Step-by-step explanation:
3/5x^4 +2/7x^3
you find the lcm of the denominators
21/35x^7 + ,10/35x^7 =31/35x^7
Answer:
12 over 15 and 1 over 15 i think
Step-by-step explanation:

(my Underscore in the wrong place)
because of it's placement n' stuff.
Then 0.5 because the numbers are halved
The fastest way is to just use a scientific calculator.
To do it without a calculator, use prime factorization.
I'll only do the second one which is the answer.
27 x 8
= 3^3 x 2^3 = 6^3
Which is a perfect cube.
Let's evaluate the equation and check if it satisfies the equality:`
6x + 4y = 36
6(3) + 4(4) = 36
18 + 16 = 36
34 ≠ 36
When x = 3 and y = 4 equality is not satisfied
