Question

Can anyone help me how to solve this?

Answer 1

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

hope it helps

Answer 2

$x^{a} * x^{b}= x^{a+b}$
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
