Question

Find the missing exponent. Set up an equation and solve. : x^4·x^n = x^5

N = missing exponent.

Please explain so I can understand.

Answer 1

1 + what =5

Answer 2

n=1

Answer 3

lol i did it backwards

Answer 4

when you multiply exponent you add them...
x^4*x^n is the same as x^(4+n)

so we can say

x^(4+n)=x^5

since the bases are the same the exponents need to equal each other...
so we can get rid of the bases:

4+n=5

now subtract 4 from both sides... and you get n=1 :)

Answer 5

n=1
x^4+x^1=x^5
