Final answer:
To evaluate the expression 4^3*(0.6+3.6)/0.3, the answer is 537.6. To evaluate the expression 2^4+(2.75+1.75)/0.9, the answer is 21.
Step-by-step explanation:
To evaluate the expression 4^3*(0.6+3.6)/0.3, we start by performing the addition within the parentheses: 0.6 + 3.6 = 4.2. Next, we can calculate 4^3 = 4 * 4 * 4 = 64. Finally, we divide 64 * 4.2 by 0.3 to get the answer:
537.6
To evaluate the expression 2^4+(2.75+1.75)/0.9, we first calculate the addition within the parentheses: 2.75 + 1.75 = 4.5. Next, we calculate 2^4 = 2 * 2 * 2 * 2 = 16. Finally, we divide 16 + 4.5 by 0.9 to get the answer:
21
