From color codes for resistors. R=21× 108Ω±5 %=2.1× 109Ω±5 % ∴ R=2.1GΩ±5 %

Q. The value of the resistance of a carbon resistor has bands of different colours as mentioned in the figure is $α G Ω \pm 5%$ . Write value of $10 α$ .

From color codes for resistors.
$R = 21 \times 1 0^{8} Ω \pm 5% = 2.1 \times 1 0^{9} Ω \pm 5%$
$∴ R = 2.1 G Ω \pm 5%$
