5 x 32 + 42 = 5 x 9 + 16 = 61
5 x 10-10 = 0.0000000005
The first five positive integer multiples of 61 are: 1 x 61 = 61 2 x 61 = 122 3 x 61 = 183 4 x 61 = 244 5 x 61 = 305
2 x 10^1 x 1 x 10^5 = 2 x 10^6
4.53 x 10 to the power of 5
614 or 61 x 61 x 61 x 61 equals 13,845,841
5 x 32 + 42 = 5 x 9 + 16 = 61
5 x 10-10 = 0.0000000005
To convert 3 x 10^-5 to an ordinary number, you need to move the decimal point to the left by 5 places. This results in the number 0.00003. This is because when a number is multiplied by 10 raised to a negative power, it shifts the decimal point to the left.
The first five positive integer multiples of 61 are: 1 x 61 = 61 2 x 61 = 122 3 x 61 = 183 4 x 61 = 244 5 x 61 = 305
61 x 10 = 610
2 x 10^1 x 1 x 10^5 = 2 x 10^6
I like to do these by setting up a proportion. Think part to whole equals part to whole: 10%/100% = x/61 (In words, 10% is to 100% as x (unknown) is to 61.) Now simply solve for x. 10%/100% = x/61 (100%)(x) = (10%)(61) ------> cross multiply (1)(x) = (0.10)(61) ------> turn percent into decimals by dividing by 100 x = 6.1 ------> simplify 10% of 61 is 6.1. Hope that helps!
5 x 10-4 = 0.0005
(5)21 x (4)11 = (5)11 x (5)10 x (4)11 = (5)10 x (5 x 4)11 = (5)10 x (20)11 =(5)10 x 20 x (20)10 = 20 x (5 x 20)10 = 20 x (100)10 = 2 x (10)1 x (10)20 =2 x (10)21 = 2,000,000,000,000,000,000,000
