Mga Hakbang ng Solution

Kalkulahin ang 2 sa power ng 7 at kunin ang 128.

$$\frac{42^{8-128}}{3\times 2^{7}+2^{9}}$$

I-subtract ang 128 mula sa 8 para makuha ang -120.

$$\frac{42^{-120}}{3\times 2^{7}+2^{9}}$$

Kalkulahin ang 42 sa power ng -120 at kunin ang \frac{1}{616474117742092901739604862821082075279154251334791631953027667573615351468401985134762850660868909307537654919202847944894677498596990672632870796344513338101989377843202107424088905150655102976}.
