Sure! Let's find the square roots for the given numbers step by step.
(a) [tex]\(\sqrt{81}\)[/tex]:
The number 81 is a perfect square since it can be expressed as the product of the integer 9, i.e., [tex]\(81 = 9 \times 9\)[/tex]. Therefore, the square root of 81 is:
[tex]\[ \sqrt{81} = 9.0 \][/tex]
(b) [tex]\(\sqrt{1}\)[/tex]:
The number 1 is a perfect square since it can be expressed as the product of the integer 1, i.e., [tex]\(1 = 1 \times 1\)[/tex]. Therefore, the square root of 1 is:
[tex]\[ \sqrt{1} = 1.0 \][/tex]
(c) [tex]\(\sqrt{121}\)[/tex]:
The number 121 is a perfect square since it can be expressed as the product of the integer 11, i.e., [tex]\(121 = 11 \times 11\)[/tex]. Therefore, the square root of 121 is:
[tex]\[ \sqrt{121} = 11.0 \][/tex]
(d) [tex]\(\sqrt{0}\)[/tex]:
The number 0 is a special case where it is its own square, i.e., [tex]\(0 = 0 \times 0\)[/tex]. Therefore, the square root of 0 is:
[tex]\[ \sqrt{0} = 0.0 \][/tex]
(e) [tex]\(\sqrt{49}\)[/tex]:
The number 49 is a perfect square since it can be expressed as the product of the integer 7, i.e., [tex]\(49 = 7 \times 7\)[/tex]. Therefore, the square root of 49 is:
[tex]\[ \sqrt{49} = 7.0 \][/tex]
In summary, the square roots are:
- [tex]\(\sqrt{81} = 9.0\)[/tex]
- [tex]\(\sqrt{1} = 1.0\)[/tex]
- [tex]\(\sqrt{121} = 11.0\)[/tex]
- [tex]\(\sqrt{0} = 0.0\)[/tex]
- [tex]\(\sqrt{49} = 7.0\)[/tex]

The number 0 is a special case where it is its own square, i.e., [tex]\(0 = 0 \times 0\)[/tex]. Therefore, the square root of 0 is:
[tex]\[ \sqrt{0} = 0.0 \][/tex]
(e) [tex]\(\sqrt{49}\)[/tex]:
The number 49 is a perfect square since it can be expressed as the product of the integer 7, i.e., [tex]\(49 = 7 \times 7\)[/tex]. Therefore, the square root of 49 is:
[tex]\[ \sqrt{49} = 7.0 \][/tex]
In summary, the square roots are:
- [tex]\(\sqrt{81} = 9.0\)[/tex]
- [tex]\(\sqrt{1} = 1.0\)[/tex]
- [tex]\(\sqrt{121} = 11.0\)[/tex]
- [tex]\(\sqrt{0} = 0.0\)[/tex]
- [tex]\(\sqrt{49} = 7.0\)[/tex]
Answer:
(a) 9
(b) 1
(c) 11
(d) 0
(e) 7
Step-by-step explanation:
Given:
- (a) √(81)
- (b) √(1)
- (c) √(121)
- (d) √(0)
- (e) √(49)
To find the square root, we need to find the number that, when multiplied by itself, equals the given value.
a) 9 * 9 = 81
Therefore, √81 = 9
b) 1 * 1 = 1
Therefore, √1 = 1
c) 11 * 11 = 121
Therefore, √121 = 11
d) 0 * 0 = 0
Therefore, √0 = 0
e) 7 * 7 = 49
Therefore, √49 = 7
