Question

Can anyone help me how to solve this?

Answer 1

`x^(a) * x^(b)= x^(a+b)`
then for
`7^(2)*7^(6)=7^(6+2)=7^(8)` then a =8 in here
and also
`3^(6)*3^(5)=3^(6+5)=3^(11)` then a =11 in this example
for
`2^(3)*2^(7)=2^(3+7)=2^(10)` then a=10 in here

Answer 2

1) 3^6 * 3^5 = 3^11
2) 2^3 * 2^7 = 2^10
3)7^2*7^6 = 7^8

hope it helps
