If i'm understanding correctly, you're asking us to evaluate 4*(x^5), with x being 2.
If that is right, then 4x^5 = 4(2^5) = 4(32) = 128
P.S.: The caret symbol (^) can be used to denote exponents

What is 4x5 but five is an exponet, when x = 2?
4x^5 = 4(2)^5 = 4 *32 = 128

That's easy
You plug in 2 for x so the equation is 4 x 2^5
Then you do 2^5 which is 32 then multiply by 4 which is 128

Remember PEMDAS (parethesis, exponents, multiply, divide, add, subtract) in that order.
Exponent first: x^5 where x=2 is 2^5 is 32
Multiply second: 4 x 32 = 128

4x^5 when x=2
4(2^5)=4*32=128
