First sixth and seventh are true
3^4
when multiplying exponents, if the bases are the same (the number that the exponent attaches to), you can simply add the exponents together.
if you were to solve the problem, you’d get the same answer
3^2 * 3^2 = 9*9 = 81
3^4 = 3*3*3*3 = 81
Answer:
Step-by-step explanation:
This is an arithmetic sequence
a1 = -2
Difference = 2nd term - first term
![=\frac{-5}{4}-[-2]\\\\=\frac{-5}{4}+2\\\\=\frac{-5}{4}+\frac{2*4}{1*4}\\\\=\frac{-5+8}{4}=\frac{3}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-5%7D%7B4%7D-%5B-2%5D%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B4%7D%2B2%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B4%7D%2B%5Cfrac%7B2%2A4%7D%7B1%2A4%7D%5C%5C%5C%5C%3D%5Cfrac%7B-5%2B8%7D%7B4%7D%3D%5Cfrac%7B3%7D%7B4%7D)

In this question, it is given that
A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.
And we have to find number of bacterias on day *.
For that we use the following formula


Substituting these values in the formula, we will get

THerefore on day 8, number of bacterias are 1579.
