Hasil perhitungan dari 2-³ + 3-² adalah….. a.2/9 b. 17/72 c. 5/18 d. 7/24

2-³ = 1/2³

3-² = 1/3²

2³ = 8

3² = 9

1/8 + 1/9 = 9/72 + 8/72 = 17/72. (B)

Jawaban:

${2}^{ - 3} + {3}^{ - 2} = frac{1}{ {2}^{3} } + frac{1}{ {3}^{2} } \ frac{1}{8} + frac{1}{9} = frac{9 + 8}{72} = frac{17}{72} \$

Jawaban B
