How can you use 2x10 to find 4x10
602,040,706
To evaluate the expression (4x10^4)(2x10^5), you first multiply the numbers 4 and 2 to get 8. Then, you multiply the powers of 10 by adding the exponents, which gives you 10^(4+5) = 10^9. Therefore, the final answer is 8x10^9.
Area = length * width width = 4*102 length = 2*103 Area = 4*102*2*103 = 8*105
2x10=2x10to the first power
No, they are not equivalent. 2x10 = 20 and 5x25 = 125.
6-2x10 is equal to -14.
No. Scientific notation is a way of expressing very large or very small digits as factors of ten (a sort of numeric abbreviation). Ie: 2x10^8 (two times ten to the eighth power) is the same as 2x10x10x10x10x10x10x10x10, or 200000000, or conversely 2x10^-8 (two times ten to the negative 8th) is .000000002 A number in scientific notation does not change the way the math is performed. Addition, subtractio, multiplication and division will still give the same answers. In direct relation to your question, 2+2 in scientific notation would be (2x10^0) x (2x10^0) and it would equal 4 (or 4x10^0)
