Question

I need this Asap Please and Thank you​

Answer 1

`a= 10,\:\: b=6`

Explanation:

• 
  `(7^2\:.\:7^8)/(7^4)=(7^a)/(7^4)=7^b`

• 
  `\rightarrow(7^(2+8))/(7^4)=(7^a)/(7^4)=7^b`

• 
  `\rightarrow(7^(10))/(7^4)=(7^a)/(7^4)=7^b`

• 
  `\rightarrow {7^(10-4)}={7^(a-4)}=7^b`

• 
  `\rightarrow {7^(6)}={7^(a-4)}=7^b`

• 
  `\rightarrow 6=a-4=b` (Bases are equal so exponents will also be equal)

• 
  `\rightarrow 6=a-4,\:\: 6=b`

• 
  `\rightarrow 6+4=a,\:\: 6=b`

• 
  `\rightarrow a= 10,\:\: b=6`
