$\\sqrt{4.84} = \\square$
$\\sqrt{4.84} = \\square$
Answer
Explanation:
Step1: Recall square of decimal
We know that to find the square root of a decimal number, we can think about which number, when multiplied by itself, gives the number inside the square root. Let's consider the number 2.2.
Step2: Calculate square of 2.2
We calculate (2.2\times2.2). (2\times2 = 4), (2\times0.2=0.4), (0.2\times2 = 0.4), (0.2\times0.2=0.04). Then, ((2 + 0.2)\times(2+0.2)=2\times2+2\times0.2 + 0.2\times2+0.2\times0.2=4 + 0.4+0.4 + 0.04 = 4.84). So, (\sqrt{4.84}=2.2)
Answer:
(2.2)
