Question

Easy question for quick medal... help please.

Answer 1

There are (3^2)^4 ⋅ 3^0 bacteria in a petri dish. What is the total number of bacteria in the dish?

Answer 2

6561

Answer 3

anything to the 0 power is just equal to 1 \[(2)^0 = 1\]
\[(x)^0 =1\]
another exponent rule \[\huge\rm (x^m)^n = x^{m \times n}\]

Answer 4

yeah I remember that ..
@Nnesha

Answer 5

@Curry that isnt right D:

Answer 6

well 9^4 * 1 = 6561

Answer 7

unless i misunderstood that?

Answer 8

I think you did unfort! I can give you the answer choices? But I'd like to see the work done with it ..

Answer 9

A) 3^8
B) 3^9
C)3^11
D)3^24

Answer 10

3^2 = 9 = 3 * 3
9^4 = 9*9*9*9 = 6561

Answer 11

well, if the base number is 3, then it'd just be 3^(2*4) = 3^8

Answer 12

Ok thanks!

Answer 13

\[\huge\rm (x^m)^n = x^{m \times n}\]
^^^ multiply outside exponent by inside exponent of the # :-)
remember :?? :3 o^_^o
btw welcome to openstudy!

Answer 14

That would give me (3^8) ⋅ 3^0 @Nnesha right?

Answer 15

yep right
and what's 3^0 = ?

Answer 16

1?

Answer 17

perfect!

Answer 18

@Nnesha ahh then what would the answer be? im a little confused. is 3^8 right?

Answer 19

did you get 3^8 ?

Answer 20

OH

Answer 21

i see

Answer 22

okay, then 3^8 is right. because (3^8) x 1 = 3^8

Answer 23

yep right

Answer 24

ahh thanks

Answer 25

np :-)
