Clara is incorrect. When you do the math, 4 squared is basically saying multiply four times four. Which equals Sixteen. When you divide Sixteen by two you get eight, not four. My math is listed below.
4^2 (4 • 4) = 16
16/2 = 8
Hopefully this helped and good luck!!
Answer:
3
Step-by-step explanation:
Following the rules of bedmas, we have to solve the brackets first.
[(18 + 3 · 2) ÷ 8 + 5 · 3] ÷ 6
[(18 + 6) ÷ 8 + 5 · 3] ÷ 6
[(24) ÷ 8 + 5 · 3] ÷ 6
- Now divide and multiply the values in the brackets.
(3 + 15) ÷ 6
(18) ÷ 6
= 3
Alright! In order to do number 3, you first have to simply what you have. So:
√4x[12-√(10-6)] → √4x[12 ÷ √4]
Now, to find the square root of a number you simply ask yourself, "What number times itself will give me that number?". So, the number two times itself is equal to 4. So:
√4 = 2. Plug in this value for √4.
2x[12 ÷ 2] → 2x6
Multiply:
2x6 = 12
Yes, 5:10 and 2:4 are equivalent.
5:10 (simplified) = 1:2
2:4 (simplified) = 1:2
Hope this helps; have a great day!
