Do 6.2 times 6.2, then 2 of the 4 are used, then do the sum times 6.2, that's another 1 used up, then do the sum of that times 6.2 and you have your answer.

Very wrong. That is 6.24 whereas the question was about 6.2*104
6.2*104 = 6.2*10000 = 62,000
62 ÷ 13 = 4 with remainder 10 OR 4.76923 times.
3.45 x 10^1
10 to the power 3+4 ie 10 to the 7th power.
10 to the zero is 1, so answer is 4
4 with 2 remaining 62 - 2 = 60 = 15 x 4
62 ÷ 13 = 4 with remainder 10 OR 4.76923 times.
10 to the 4 power times 10 to the 3 power is 10,000,000 (10 million).
3.45 x 10^1
(4 x 10 )3 = 64,000 4 x 103 = 4000. It depends if the question is 4 times -----10 to the third power or 4 times ten ----- to the third power.
10 to the power 3+4 ie 10 to the 7th power.
62/4 = 15.5
the answer is 300
4 x 102 = 400
10 power of 4
4 goes into 62 15.5 times
10 to the zero is 1, so answer is 4
4 x 10-5 = 0.00004
