tolong di jawab yaa soal nya mau di kumpul kan
5. A. 571
6. B. 85
7. C. 170
Penyelesaian :
[tex]23 {}^{2} + \sqrt{1.764} [/tex]
[tex] = (23 \times 23) + \sqrt{1.764} [/tex]
[tex] = 529 + \sqrt{1.764} [/tex]
[tex] = 529 + 42[/tex]
[tex] = 571[/tex]
6.
[tex] \sqrt{432 + 352} + 11 {}^{2} - 8 {}^{2} [/tex]
[tex] = \sqrt{784} + 11 {}^{2} - 8 {}^{2} [/tex]
[tex] = 28 + (11 \times 11) - (8 \times 8)[/tex]
[tex] =( 28 + 121 )- 64[/tex]
[tex] = 149 - 64[/tex]
[tex] = 85[/tex]
7.
[tex]18 {}^{3} \div 3 {}^{3} - \sqrt[3]{97.336} [/tex]
[tex] = (18 \times 18 \times 18) \div (3 \times 3 \times 3) - \sqrt[3]{97.336} [/tex]
[tex] = (\frac{582}{27}) - \sqrt[3]{97.336} [/tex]
[tex] = 216 - \sqrt[3]{97.336} [/tex]
[tex] = 216 - 46[/tex]
[tex] = 170[/tex]
