3 x (10 to power of -5) = 3/(10 to power of 5) = 3/100000 = 0.00003
1000 = 1X 10(to the power of 3) 500 = 5 x 10(to the power of 2) 30 = 3 x 10(to the power of 1) 3 = 3 x 10(to the power of 0)
3×10¹⁵ ÷ 6×10¹⁰ = (3 ÷ 6)×(10¹⁵÷10¹⁰) = 0.5×10¹⁵⁻¹⁰ = (5×10⁻¹)×10⁵ = 5×10⁻¹⁺⁵ = 5×10⁴ It is 5×10⁴ (= 50,000) times bigger.
5.0 × 10-3 is 0.0050
The GCF is 2^3 x 3^2 x 5
3 x (10 to power of -5) = 3/(10 to power of 5) = 3/100000 = 0.00003
1000 = 1X 10(to the power of 3) 500 = 5 x 10(to the power of 2) 30 = 3 x 10(to the power of 1) 3 = 3 x 10(to the power of 0)
4-3 x 4-5 = 1.5265625 × 10-5
92,054,000 is the answer.
Three significant figures of 1.702 x 10^5 are 1.70 x 10^5.
In words: three million, nine hundred and eighty five thousand, eight hundred. In numbers: 3 000 000 + 900 000 + 80 000 + 5000 + 800 In powers: 3 x 10 to the power of 6 + 9 x 10 to the power of 5 + 8 x 10 to the power of 4 + 5 x 10 to the power of 3 + 8 x 10 to the power of 2.
3×10¹⁵ ÷ 6×10¹⁰ = (3 ÷ 6)×(10¹⁵÷10¹⁰) = 0.5×10¹⁵⁻¹⁰ = (5×10⁻¹)×10⁵ = 5×10⁻¹⁺⁵ = 5×10⁴ It is 5×10⁴ (= 50,000) times bigger.
5.93 x 10^3
5.0 × 10-3 is 0.0050
5,000
10 to the power 3 = 1000
9.89 exp-1 (9.89 times 10 to the -1 power)
