[tex]4 ^ \frac{1}{2} \times 4^{ - 1} [/tex]bagaimana penyelesaian

Berikut ini adalah pertanyaan dari sagitasekarningrum pada mata pelajaran Matematika untuk jenjang Sekolah Menengah Atas

4 ^ \frac{1}{2} \times 4^{ - 1}
bagaimana penyelesaian nya​

Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Sifat-sifat perpangkatan:

\boxed{\begin{array}{c}{\rm {a}^{m}\times{a}^{n}={a}^{m+n}}\\\rm {a}^{m}\div{a}^{n}={a}^{m-n}\\\rm {({a}^{m})}^{n}={a}^{m\times n}\\\rm {a}^{\frac{m}{n}}=\sqrt[n]{{a}^{m}}\\\rm {a}^{-m}=\frac{1}{{a}^{m}}\\\rm {(\frac{a}{b})}^{-m}={(\frac{b}{a})}^{m}\\\rm {(\frac{a}{b})}^{m}=\frac{{a}^{m}}{{b}^{m}}\end{array}}

Jawaban:

{4}^{ \frac{1}{2} } \times {4}^{ - 1} = {4}^{ \frac{1}{2} + ( - 1) } = {4}^{ - (1 - \frac{1}{2}) } = {4}^{ - \frac{1}{2} }

= \frac{1}{ {4}^{ \frac{1}{2} } } = \frac{1}{ \sqrt{4} } = \frac{1}{2}

Jawaban: ½.

Semoga membantu
