3.45 x 10^1
23 000. This is standard form and should be written as: 23 x 10^2. (The ^ denotes an exponent.)
10² × 0.23 = 10 × 10 × 0.23 = 100 × 0.23 = 23 The quick way to do this is to note that the power of 10 is (positive) 2, so move the decimal point 2 places to the right → 10² × 0.23 = 23
6.0 x 1023 equals 600,000,000,000,000,000,000,000
15, 3 multiplied by 15 equals 4545 ÷ 3 = 15
13 x 23 x 19 x 15 = 85215
8.45 x 10^23 = 845,000,000,000,000,000,000,000
23 times 15 = 120
100,000,000,000,000,000,000,000
The result is 3.0066445 x 1046
It is 6.02 (times) 10 to the power of 23
23 000. This is standard form and should be written as: 23 x 10^2. (The ^ denotes an exponent.)
10² × 0.23 = 10 × 10 × 0.23 = 100 × 0.23 = 23 The quick way to do this is to note that the power of 10 is (positive) 2, so move the decimal point 2 places to the right → 10² × 0.23 = 23
10 18 15 23 20
6.0 x 1023 equals 600,000,000,000,000,000,000,000
