Answer:
3x - (15 x 3) = 90
or
3x - 45 = 90
Explanation:
there are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45
Therefore the first part is 3x - 45
We also know that in the end we have 90 left.
So our final equation is:
3x - 45 = 90
The expression given in the question is expressed as a power is x^10
According to the law of indices, multiplication of powers becomes addition as shown:
![a^m \times a^n = a^{m+n}](https://tex.z-dn.net/?f=a%5Em%20%5Ctimes%20a%5En%20%3D%20a%5E%7Bm%2Bn%7D)
Given the following expressions;
![xx^4x^4x](https://tex.z-dn.net/?f=xx%5E4x%5E4x)
This can also be expressed as:
![= x \times x^4 \times x^4 \times x\\= x^{1+4+4+1}\\=x^{5+5}\\=x^{10](https://tex.z-dn.net/?f=%3D%20x%20%5Ctimes%20x%5E4%20%5Ctimes%20x%5E4%20%5Ctimes%20x%5C%5C%3D%20x%5E%7B1%2B4%2B4%2B1%7D%5C%5C%3Dx%5E%7B5%2B5%7D%5C%5C%3Dx%5E%7B10)
This shows that the expression as power is x^10
