Jawaban:

sin(30°) × cos(60°) + 4^(-2)

=1/2 × 1/2 + 1/4²

=(1/2)^(1+1) + 1/(4×4)

= (1/2)² + 1/16

= 1²/2² + 1/16

= 1/(2×2) + 1/16

= 1/4 + 1/16

= 4/16 + 1/16

= (4+1)/16

= 5/16

 sf sin( {30}^{ circ} ) times cos( {60}^{ circ} ) + {4}^{ - 2}

 sf = cfrac{1}{2} times dfrac{1}{2} + dfrac{1}{ {4}^{2} }

 sf = left(cfrac{1}{2} times dfrac{1}{2} right)+ dfrac{1}{4 times 4}

 sf = cfrac{1}{4} + dfrac{1}{16 }

 sf = cfrac{1 times 4}{4 times 4} + dfrac{1}{16 }

 sf = cfrac{4}{16} + dfrac{1}{16 }

 sf = cfrac{4 + 1}{16}

 sf = cfrac{5}{16}
