heyyyyyyyy i didddddddddddddddddd
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
7/x - 3/(2x) + 7/6 = 9/x
x(7/x - 3/(2x) + 7/6) = x(9x)
x*7/x - 3*x/(2x) + x*7/6 = x*9x
7 - 3/2 + 7x/6 = 9
7x/6 = 9 - 7 + 3/2
7x/6 = 2 + 3/2
7x/6 = 12/6 + 9/6
7x = 12+9
7x = 21
x = 21/7
x = 3
probe:
7/3 - 3/(2*3) + 7/6 = 9/3
14/6 - 3/6 + 7/6 = 3
(14 - 3 + 7) / 6 = 3
18/6 = 3
Answer:
- 2⁻⁶
Step-by-step explanation:
To simplify this we have to know the following rules.
(i) (xᵃ)ᵇ = xᵃᵇ
(ii) 1/xᵃ = x⁻ᵃ
Given: 
= 
= 
= 
[using (i)]
= 
[using (ii)]
Hence, the simplified form would be:
