soebeqi Jawaban no. 1.
$\frac{ 21 {a}^{ - 4} {b}^{ - 3} c}{3 {a}^{ - 7} {b}^{ - 6} {c}^{ - 2} } = \frac{21}{3} ({a}^{( - 4 - ( - 7))} {b}^{( - 3 - ( - 6)} {c}^{(1 - ( - 2))}) \\ \frac{ 21 {a}^{ - 4} {b}^{ - 3} c}{3 {a}^{ - 7} {b}^{ - 6} {c}^{ - 2} } = 7 ({a}^{( - 4 + 7)} {b}^{( - 3 + 6)} {c}^{(1 + 2))}) \\ \frac{ 21 {a}^{ - 4} {b}^{ - 3} c}{3 {a}^{ - 7} {b}^{ - 6} {c}^{ - 2} } = 7 {a}^{3} {b}^{3} {c}^{3}\\$

Jawaban no. 2.

$( {\frac{ {a}^{ \frac{1}{4} } {b}^{ - 4} }{ {a}^{ - 3} {b}^{ \frac{3}{4} } } } )^{ \frac{2}{4} } = {( {a}^{ (\frac{1}{4} - ( - 3))} {b}^{ (- 4 - (\frac{3}{4} ))} )}^{ \frac{1}{2} } \\ ( {\frac{ {a}^{ \frac{1}{4} } {b}^{ - 4} }{ {a}^{ - 3} {b}^{ \frac{3}{4} } } } )^{ \frac{2}{4} } = {( {a}^{ (\frac{1}{4} + \frac{12}{4} )} {b}^{ (- \frac{16}{4} - \frac{3}{4} )} )}^{ \frac{1}{2} } \\ ( {\frac{ {a}^{ \frac{1}{4} } {b}^{ - 4} }{ {a}^{ - 3} {b}^{ \frac{3}{4} } } } )^{ \frac{2}{4} } = {( {a}^{ (\frac{13}{4} )} {b}^{ (- \frac{19}{4} )} )}^{ \frac{1}{2} } \\ ( {\frac{ {a}^{ \frac{1}{4} } {b}^{ - 4} }{ {a}^{ - 3} {b}^{ \frac{3}{4} } } } )^{ \frac{2}{4} } = {( {a}^{13} {b}^{ - 19} )}^{ \frac{1}{8} } \\ ( {\frac{ {a}^{ \frac{1}{4} } {b}^{ - 4} }{ {a}^{ - 3} {b}^{ \frac{3}{4} } } } )^{ \frac{2}{4} } = \sqrt[8] {( {a}^{13} {b}^{ - 19} )} \\$

Jawaban no. 3

$\sqrt{81} + 2 \sqrt{36} - \sqrt{18} = 9 + 2 \times 6 - \sqrt{9 \times 2} \\\sqrt{81} + 2 \sqrt{36} - \sqrt{18} = 9 + 12 - 3\sqrt{2} \\\sqrt{81} + 2 \sqrt{36} - \sqrt{18} = 21 - 3\sqrt{2}$

Jawaban no.4

$\frac{5}{2 + \sqrt{3}} = \frac{5}{2 + \sqrt{3}} \times \frac{2 - \sqrt{3}}{2 - \sqrt{3}} \\\frac{5}{2 + \sqrt{3}} = \frac{5 (2 - \sqrt{3})}{(2\times2) + \sqrt{3} - \sqrt{3} +(\sqrt{3} \times \sqrt{3})} \\\frac{5}{2 + \sqrt{3}} = \frac{5(2 - \sqrt{3})}{4 + 3} \\\frac{5}{2 + \sqrt{3}} = \frac{5}{8} (2 - \sqrt{3})$

Jawaban no. 6

$^{4}log(28) - ^{4}log(7) + ^{4}log(8) + ^{4}log(6) = ^{4}log(28 - 7 + 8 + 6) \\^{4}log(28) - ^{4}log(7) + ^{4}log(8) + ^{4}log(6) = ^{4}log(35)$

Jawaban no.7

$^{3}log(9) + ^{3}log(3) - ^{3}log(27) = ^{3}log(9 + 3 - 27) \\^{3}log(9) + ^{3}log(3) - ^{3}log(27) = ^{3}log(-15)$

Jawaban no. 10

5x + 3 = 3x - 7
5x - 3x = - 7 - 3
2x = -10
x = -10/2
x = -5

Hanya bisa bantu jawab segitu saja. Semoga bermanfaat.
