A1 It means 1x103 = 1000 (three zeroes after the one)
A2 To understand why this is so, the expression 'to the power of' just means that the number concerned is multiplied by itself the appropriate number of times. Thus '10 to the power of three' means 10 x 10 x 10 which equals 1000. Scientists often use this as a shorthand way of writing large numbers.
the power of 10 mean 10 100 1,000 100,000 the power of 10 mean 10 100 1,000 100,000
you have a special power when you reach the age 10 if your past it start studying
1000ten to the power of three is 1000 because the three indicates the number of zeros
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.
When a whole number is multiplied by a power of ten, the number's digits shift to the left by the number of zeros in the power of ten. In this case, multiplying 5000 by 10^3 (which is 10 raised to the power of 3, or 1000) results in 5000 shifted three places to the left, becoming 5,000,000. This is because 10^3 has three zeros.
the power of 10 mean 10 100 1,000 100,000 the power of 10 mean 10 100 1,000 100,000

1,000 = 10 x 10 x 10
10-3 = 0.001
1000ten to the power of three is 1000 because the three indicates the number of zeros
3x3x3x3
10 to the power of 390 is greater than 10 to the power of 320.
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.
3 x 10-10 equates to 0.0000000003 (three ten-billionths).
By 'a power' I would understand you to mean a number raised to a power, such as 43. You can then refer to this as 'four to the power of three'
103 = 1000 10-3 = 0.001 or 1/1000
Negative power of10 is a number which is 10% of its previous number. Like 10 power -1 = 0.1 10 power -2 = 10% of 0.1=0.01 10 power -3 = 10% of 0.01=0.001
