Question
IC chips used in computers are usually made
of:Solution
Most ICs are made of silicon, which is abundant in ordinary beach sand. Pure crystalline silicon, as with other semiconducting materials, has a very high resistance to electrical current at normal room temperature
65% of 102 + 14 = ? – 20
808 ÷ (128)1/7 + 482 = 4 × ? + 846
((8)0- (0.1)-1)/( (6/16)-1 ×(3/2)3+ ((-2)/6)-1) = ?/2
(36/8)2 × (912/38) ÷ (122/1586) = ?
...125% of 129 ÷ 43 × 28 ÷ 7 = ? ÷ √16
13 X ? = 85 X 4 + √81 + 2
54% of 250 = 6 × 21 + √?
15% of 360 × 20% of ? = 324
10 * 15 + 30% of 150 + 80% of 200 = ?
1299.999 ÷ 325.018 × 24.996 = ?
