Question

Find the product
7n^4 * 2n^5

Answer 1

when you mulitplyc same bases you should add their exponents
exxample
\[\huge\rm x^m \times x^n = x^{m+n}\]

Answer 2

i mean 14^9

Answer 3

9? to the 9 power ?
multiply coefficient
(7 times 2)(n^4 times x^5)

Answer 4

14 is not to the 9 power
the variable is to the 9 poawer

Answer 5

i am still so confused

Answer 6

so like 14^20

Answer 7

nope 9 is right bec you have to add exponents
so n^9 not 14^9

Answer 8

okay so it would be 14n^9

Answer 9

\[\huge\rm (7 \times 2)(n^4 \times n^5)=(7 \times 2) n^{4+5}\]

Answer 10

yes that's right

Answer 11

5xy^5 * -3x^4y^3 how would that one be set up to find the product

Answer 12

* <--is that a multiplicationz sign ?

Answer 13

yea

Answer 14

that's same like we just did
multiply coefficients and add exponents of variables

Answer 15

x is same as x to the one power
x=x^1

Answer 16

so it would be like -15^xy13? or -15x^5y8

Answer 17

-15x^5y^8 i wrote that wrong

Answer 18

add coefficient of same variables
you can't add 3 exponent of y with 5 exponent of x
x^{1+4}

Answer 19

so which one is correct ?

Answer 20

so it would be -15x^5y^8

Answer 21

thank you it was right

Answer 22

np :=)
