2^8-10-15÷3

can you help me pl

241

Step-by-step explanation:

Simplify the following:

2^8 - 10 - 15/3

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

2^8 - 10 + -5

2^8 = (2^4)^2 = ((2^2)^2)^2:

((2^2)^2)^2 - 10 - 5

2^2 = 4:

(4^2)^2 - 10 - 5

4^2 = 16:

16^2 - 10 - 5

1 | 6 | 0

2 | 5 | 6:

256 - 10 - 5

256 - 10 - 5 = 256 - (10 + 5):

256 - (10 + 5)

10 + 5 = 15:

256 - 15
