Hey there,
Pretend that 50 = 100
And that 5 = 10.
I did a 100 test unit test, and I got 10% wrong.
If you think about this, the answer would be 90%
So, it's the same in this case,
50 in half of 100
5 is half of 10.
So . . .
This would mean that your correct answer would be 90% because 5 in this case is to be considered to be 10.
Your correct answer is
. . . .

Hope this helps

Answer:
Step-by-step explanation:
PEDMAS
P - Parenthesis
E - Exponents
D - Division
M - Multiplication
A - Addition
So, 2(5-3)^3+6^2
5 - 3 should be completed first as it is inside parenthesis
2(5-3)^3+6^2 = 2 *2^3 + 6^2
= 2 * 8 + 36 {exponents}
= 16 + 36 {Multiplication}
= 52
