Tumia jedwali za logariti kwa usahihi hadi tarakimu 4 muhimu kutathmini: 3/(69.8)

Haya hapa majibu ya maswali yako:

1. Tumia jedwali za logariti kwa usahihi hadi tarakimu 4 muhimu kutathmini: $\sqrt[3]{\frac{0.07214 \times 2.037}{69.8}}$

• Hatua ya 1: Weka usemi kama $x$ na utumie logariti.

  $$x = \sqrt[3]{\frac{0.07214 \times 2.037}{69.8}}$$ $$\log_{10} x = \frac{1}{3} \left( \log_{10}(0.07214) + \log_{10}(2.037) - \log_{10}(69.8) \right)$$

• Hatua ya 2: Tafuta logariti za nambari kutoka jedwali.

  $$\log_{10}(0.07214) = \bar{2}.8581$$ $$\log_{10}(2.037) = 0.3090$$ $$$$
