Question

Please help I’ll mark brainlyest.

Answer 1

Step-by-step explanation:

We gotta mess with those exponents and their bases!

Remember that $2^2 = 4$

So $4^2$ can be written as $(2^2)^2$

We just substitued 4 for $2^2$.

Now remember that that lonely 2 has a hidden exponent of 1. $2 = 2^1$

So we have $2^1 + (2^2)^2$

Remember what we do with exponents raised to exponents? We MULTIPLY them, so we get. $2^1.+ 2^4$

Now we can just add the exponents.

$2^{1+4} = 2^5$

I think I spot a winner.

Answer 2

Answer:

3^2 + 9

Step-by-step

Since 2+4^2 is 16+2 which is 18 you need to find the expression equivalent to 18.25 doesn't work so eliminate that right away. 9^2=81 so that isn't right either. 2^3+9=17 so that is incorrect. Lastly, 3^2+9=18 so that is the correct answer.
