tolong jawab dong... pliss.. dari nomor 1 smpai nomor 7 yaa:) pake cara..

4. 4xy - 12yz - 8xz - 6xy - 3yz + xz

4xy - 6xy - 12yz - 3yz - 8xz + xz

-2xy -15yz -7xz

no 1
[tex] = {2}^{4} - {2}^{3} + {10}^{1} \\ = 16 - 8 + 10 = 18[/tex]
no 2
[tex] = \sqrt{64 \times 2} - 3 \sqrt{25 \times 2} + 4 \sqrt{4 \times 2} - 3\sqrt{9 \times 2} \\ = 8 \sqrt{2} - 15 \sqrt{2} + 8 \sqrt{2} - 9 \sqrt{2} \\ = - 8 \sqrt{2} [/tex]
no 3
[tex] \frac{ {6}^{2} }{ {3}^{2} + {2}^{3} } \\ = \frac{36}{17} [/tex]
