minta tolong dijawab.Terimakasih
Penjelasan dengan langkah-langkah:
5.
[tex](2 \times 4) ({a}^{6 + 5} )( {b}^{1 + 3} ) = 8 {a}^{11} {b}^{4} [/tex]
6.
[tex] {2}^{x + 2} =( { {2}^{x + 2} })^{ - 1} \\ \\ {2}^{x + 2} = {2}^{ - x - 2}
\\ x + 2 = - x - 2 \\ x + x = - 2 - 2 \\ 2x = - 4 \\ x = - 4 \div 2 = - 2[/tex]
7.
[tex] \sqrt{ {4}^{x + 1} } = \frac{1}{2} \\ \\ ({ \sqrt{ {4}^{x + 1} } })^{2} = ( { \frac{1}{2} })^{2} \\ ({ {4}^{x + 1} }) = \frac{1}{4} \\ {4}^{x + 1} = {4 }^{ - 1} \\ x + 1 = - 1 \\ x = - 1 - 1 = - 2[/tex]
