when you have r^4+r^4 what do you get.?

Question

i dont wan to hear how easy the question is thanks:)

Answer 1

2r^4 for sure.

because you have TWO r^4's

you can check by putting a random number such as 2 in. :]

like:
2^4+2^4=16+16=32

if it equaled 2r^4 then it'd be:
2(2)^4=2(16)=32

if it equaled r^8 then it'd be:
2*2*2*2*2*2*2*2=4*4*4*4=16*16=256

Answer 2

1 apple + 1 apple = 2 apples
1 r^4 + 1 r^4 = 2 r^4

Answer 3

Variables raised to a power are simply added together.

r^4+r^4= r^8 <------These are added because the variable is the same.

Suppose you have (x5)(x6); how do you simplify that? Just remember that you’re counting factors.

x5 = (x)(x)(x)(x)(x) and x6 = (x)(x)(x)(x)(x)(x)

Now multiply them together:

(x5)(x6) = (x)(x)(x)(x)(x)(x)(x)(x)(x)(x)(x) = x11

Why x11? Well, how many x’s are there? Five x factors from x5, and six x factors from x6, makes 11 x factors total. Can you see that whenever you multiply any two powers of the same base, you end up with a number of factors equal to the total of the two powers? In other words, when the bases are the same, you find the new power by just adding the exponents


THERE ARE DEFINITELY SOME PEOPLE IN HERE WHO NEED TO GO BACK TO ALGEBRA 1

Answer 4

2r^4.

think of it this way: replace r^4 with any variable you want. let's say x. so now, you have x + x, which you know is 2x. so now, all you need to do is go back and re-substitute r^4 back for x.

oh, by the way, the 2 is NOT being raised to the 4th power. the exponent only applies to the r.

Answer 5

2r^4 I think it is nor r^8 that is multiplication of exponents.

Answer 6

2r^4 haha

Answer 7

2(r^4), definitely not (r^8)

Answer 8

2r^4

Answer 9

2r^4

100% positive... u do not change the exponent when adding them.

Answer 10

2(r^4)

I think...
