Question

I challenge you....for the process
If a^b=b^a and a=2b then find the value of a^2+b^2.
Please show the process answer.
The most satisfying answer will be made brainliest.
The answer is 20 and a=4 , b=2

Answer 1

Okay, here goes...step by step

a^b = b^a and a = 2b

Thus by substitution

(2b)^b = b^(2b)

2^b x b^b = (b^b)^2

Now divide by b^b and get

2^b = b^b

Thus b = 2

and

a = 4

please mark me as brainliest. i need only 2 more to rank up

Answer 2

Answer:

Hope it helps you.

Need some brainliest answers.
