3.45 x 10^1
10 to the zero is 1, so answer is 4
10 to the 3rd power is 1000, so 4000.
Well, darling, 4 times 10 to the 4th power is 40,000. It's as simple as that. Math doesn't have to be a drama, just multiply the 4 by the number of zeroes in 10 to the 4th power, and voila, you've got your answer.
4,000
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.
the answer is 300
4 x 102 = 400
10 power of 4
10 to the zero is 1, so answer is 4
4 x 10-5 = 0.00004
