Huu hapa ni utatuzi wa swali la 4:

Tunatakiwa kutathmini usemi $1000 \sqrt{\frac{0.0128}{200}}$ bila kutumia jedwali au kikokotozi.

Rahisisha sehemu ndani ya mzizi wa mraba.
$\frac{0.0128}{200}$
Ili kurahisisha hesabu, tunaweza kuandika 0.0128 kama $128 \times 10^{-4}$ .
$\frac{128 \times 10^{-4}}{200} = \frac{128}{2 \times 100} \times 10^{-4} = \frac{64}{100} \times 10^{-4} = 64 \times 10^{-2} \times 10^{-4} = 64 \times 10^{-6}$
Hii ni sawa na 0.000064.
Tafuta mzizi wa mraba wa namba iliyorahisishwa.
$\sqrt{0.000064} = \sqrt{64 \times 10^{-6}}$
Tunajua kwamba $\sqrt{64} = 8$ na $\sqrt{10^{-6}} = 10^{-3}$ .
$\sqrt{64 \times 10^{-6}} = 8 \times 10^{-3} = 0.008$
Zidisha matokeo kwa 1000.
$1000 \times 0.008$ $1000 \times 0.008 = 8$
Jibu la mwisho ni:
$\text{8}$
