Rewritten in algebraic form: 4 * 1010 = 4 * 10,000,000,000 = 40,000,000,000 (forty billion).
It is: 4 times 90.25 = 361
2.4 × 10-4 written in standard form is 0.00024
It is: (81*9*64)+19 = 46,675
2.78 times 10 to the power of 4, or 2.78x104
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.
Well, darling, when you multiply numbers with the same base, you just add their exponents. So, 10 to the 3rd power times 10 to the 4th power is 10 to the 7th power. Math doesn't have to be a drag, honey!
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
Anything to the power 0 is 1. 4 × 10^0 = 4 × 1 = 4.
0.00040
4 * 109 = 4,000,000,000
