Hi!
When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).
Let's do an example.
16/8 : 4/6 = 16/8 * 6/4
Where necessary you can do cross-semplifying.
So, 16 and 4 can be divided both for 4.
8 and 6 both for 2.
So we have 4/4*3/1
You can also semplify numerator and denominator...
4/4 = 1
1*3 = 3
Answer:
55-276x
Step-by-step explanation:
To solve this question, you will have to follow some specific principles to prevent error
So to solve this we will have to follow the BODMAS rule
9-3(45x+47x)-2+66
Deal with the bracket first
3(45x+47x)
3(92x)
276x
Then back to the question
9-276x-2+66
Collect like terms
9-2+66-276x
Add comes before substration according to bodmas
9+64-276x
55-276x
This cannot be solved further because they are different from each other
Therefore the final answer is 55-276x
Answer:
729
Step-by-step explanation:
3 to the power of 2 means 3 * 3 which is 9. 3 to the power of 4 means 3 * 3 * 3 * 3 which is 81. Finally, 9 * 81 which gives you 729.
