Answer:
1. 26
2. 3.1 million
3. 12.5
Step-by-step explanation:
1. First, let’s find the square roots:
(\sqrt{64} = 8)
(\sqrt{25} = 5)
Now add the square roots:
(8 + 5 = 13)
Finally, multiply the result by 2:
(2 \cdot 13 = 26)
2. Perform the subtraction of the scientific notation terms:
(3.6 \times 10^6 - 5.2 \times 10^5 = 3.1 \times 10^6)
3. Follow the order of operations (PEMDAS/BODMAS):
First, calculate the exponent: (3^3 = 27)
Next, perform the addition and subtraction: (27 + 1 + 22 - 0 = 50)
Finally, divide by 4: (50 \div 4 = 12.5)
