Question 251289
If I am reading the problem correctly, you want to multiply 16x5 and 28x^6
 
16x^5 *28x^6
16*28*x^5*x^6

think about it x^2*x^3=32
x^1=x
x^2=x*x
x^3=x*x*x

we want x^2*x^3=x*x * x*x*x= x^5 
let's test that with 2
2^2=4
2^3=8
4*8=32
2^4=14
2^5=32
32=2^5


so when we multiply x's we add the exponents
so
x^5*x^6=x^11
16*28*x^11
