Answer:
a = 5/6 , b = -3/10
Step-by-step explanation:
3a-5b:3a+5b=1:4
3a-5b / 3a +5b = 1/4
Cross multiply
3a -5b =4 ..........(1) solve simultaneously
3a + 5b = 1 ..........(2) using elimination method
-----------------------
Add equation 1 and 2
6a = 5
Divide both sides by 6
6a/6 = 5/6
a =5/6
Put value of a into equation 2
3a +5b = 1
3(5/6) + 5b = 1
5/2 + 5b = 1
5b = 1 - 5/2
5b = - 1½
5b = - 3/2
Divide both sides by 5
5b/ 5 = -3/2 ÷ 5
b = -3/2 × ¹/5
b = - 3/10
Therefore a = 5/6 , b = -3/10

Answer:
n = 6 , m = 8.
Step-by-step explanation:
⁸√5⁶ = (5^1/8)^6
The 8 is the denominator of the exponent and the 6 is the numerator.
n = 6 , m = 8.
The terms that come from expansion through Pascal's Triangle are x^3+9x^2+27x+27. The third term in this sequence is 27x. This is your answer.

Answer:
945 ways
Step-by-step explanation:
<u>Total</u>
- Number of Appetizers = 7

<u>Required Selection</u>
- Number of Appetizers = 2
- Number of main courses = 8
- Number of desserts =4
2 Appetizers out of 7 can be selected in 
ways
8 main courses out of 9 can be selected in 
ways
4 desserts out of 5 can be selected in 
ways
Therefore, the number of ways this can be done
=945 ways
