Simplify each expression
√1.96
I recognize 196 as 14^2
so √1.96 = 1.4
Thank you, How did you see that as I am still learning how to do Sq,roots DFo I multiply 1.96 by itself?
no, you multiply 1.4 by itself to get 1.96
just like for √25 , ask yourself
"what must I multiply by itself to get 25" ?
clearly 5x5 = 25
so √25 = 5
or
just use your calculator if you don't recognize perfect squares, which are
1, 4, 9, 16, 25, 36, etc
Oh I see Thank you, that helps me understand what I did wrong. Thank you very much
To simplify the expression √1.96, you need to find the square root of 1.96.
One way to find the square root is by using a calculator. Simply enter 1.96 into the calculator and then press the square root button. The calculator will give you the simplified value.
Alternatively, you can use a method called prime factorization to simplify the expression.
1.96 can be written as a product of its prime factors:
1.96 = 2 * 2 * 7 * 7
Next, pair up the prime factors in groups of two:
(2 * 2) * (7 * 7)
Simplify each pair of prime factors by taking the square root:
2 * 7 = 14
Therefore, the square root of 1.96 is 14.
