does 3^4 equal the same sum as 4^3

Answers

No. 3^4 is 81 and 4^3 is 64.

Explanation:
3^4 means 3 to the 4th power. That would mean multiplying 3 by itself 4 times. Don’t get it confused with 3 x 4. Each time you multiply, the next time will multiply by itself. Basically 3 x 4 is 12, then 12 x 4 is 48, and so on.

Can someone plz help me with this????

Answers

what information are you given??

Answer:

since we cant see what info is given maybe these tips can help...

the 'b' is also called the y-intercept, the y-int is what you start of with. Example, if your parents give you $20 and you spend $5 every week, your y-int is 20

The m is the slope, so if your parents give you $20 and you spend $5 every week, your slope is -5 because your money is decreasing at a linear rate

the x is the input, so if you want to know how much money you have 2 weeks after you got $20, you would substitute x with 2, and solve to get $10
