Answer:
a) will definitely be an odd number
Step-by-step explanation:
4^n is always even (when you multiply even and even number, the product is always even)
when you add one to even number, the sum is always odd
so 4^n +1 is odd.
Step-by-step explanation: [(60 – 15) • 60] + 25} = 45.60 +25
=2725
45 + 22 ÷ 11. 2725
45 + 2 . 2725
45+ 5450
=5495
