Jawaban:
No.1
[tex]\sf \: \sqrt{3.249} + \sqrt{1.764} + \sqrt{625} [/tex]
[tex]\sf = 57 + 42 + 25[/tex]
[tex]\sf \: = 99 - 25[/tex]
[tex]\sf = 74[/tex]
No.2
[tex]\sf \sqrt{4.225} - \sqrt{1.764} [/tex]
[tex]\sf = 65 - 42[/tex]
[tex]\sf = 23[/tex]
No.3
[tex]\sf \sqrt{576} + \sqrt{1.024} [/tex]
[tex]\sf = 24 + 32[/tex]
[tex]\sf = 56[/tex]
No.4
[tex]\sf {76}^{2} + \sqrt{2.916} - {12}^{2} [/tex]
[tex]\sf = (76 \times 76) + 54 - (12 \times 12)[/tex]
[tex]\sf = 5.776 + 54 - 144[/tex]
[tex]\sf = 5.830 - 144[/tex]
[tex]\sf = 5.686[/tex]
No.5
[tex]\sf \sqrt{576} - \sqrt{484} [/tex]
[tex]\sf = 24 - 22[/tex]
[tex]\sf = 2[/tex]
Jawab:
1.57 + 42 - 25 = 74
2. 65 - 42 = 23
3. 24 + 10 = 34
4. 5776 + 54 - 144 = 5686
5. 24 - 22 = 2
