Answer:
(-36 x^3)/25
Step-by-step explanation:
Simplify the following:
(-4×9 x^2 x)/(5×5)
Combine powers. (9 x (-4) x^2)/(5×5) = (9 x^(2 + 1) 4 (-1))/(5×5):
-(9×4 x^(2 + 1))/(5×5)
2 + 1 = 3:
((-9×4 x^3)/5)/5
9 (-4) = -36:
(-36 x^3)/(5×5)
5×5 = 25:
Answer: (-36 x^3)/25
Answer:
10
Step-by-step explanation:
The distance can be calculated with 
The simplified fraction is
.
Solution:
Given expression:


Let x = 8.33333... -------- (1)
Multiply by 10 on both sides.
10x = 83.3333... -------- (2)
Subtract (1) from (2),
10x - x = 83.3333... - 8.33333...
9x = 75
Divide by 7 on both sides, we get


Cancel the common factor 3.


Hence the simplified fraction is
.
