Question

Simplify this expression.

Answer 1

where is the expression?

Answer 2

\[m ^{16} * m ^{6}=\]

Answer 3

m^22

Answer 4

m^(16+6) = m^(22)

Answer 5

General formula:
\[x^a \times x^b = x^{a+b}\]

Answer 6

Consider the following:
\[x^2x^3\]
So how do we combine these? What's the rule? do we add or multiply the exponents?

Take a second to examine it, and you'll realize, hey, this isn't so bad:
x^2=x∗x
x^3=x∗x∗x
so simply,
x^2*x^3=x∗x∗x∗x∗x
That's just 5 x's multiplied by each other, so knowing that, you know can just add exponents together when you have the same term with different exponents multiplied by each other.

If you ever forget, just expand it out like I did to check for yourself.

Answer 7

But the answer choices are
A.\[m ^{19}\]
B.\[m ^{7}\]
C.\[m ^{18}\]
D.\[m ^{8}\]

Answer 8

E. \[m^{22}\]

Answer 9

so it can't be m^22

Answer 10

There is only a-d

Answer 11

Good luck arguing with a calculator...

Answer 12

Lol i'm not trying to argue....IT's a multiple choice question..and there isn't 22 on it.

Answer 13

are you sure you typed the problem correctly?
people often think they are sure when they are not

Answer 14

^I agree

Answer 15

O.o i'll check :X

Answer 16

\[m ^{13}*m ^{6}=\]

Answer 17

tadah!

Answer 18

m^19

Answer 19

(: Thank's guys! And thank you TurningTest for pointing that out :D
