Which of the following is the same as 8.4 × 10²

Idk what the answer choices is if there is any

Scientific notation is 8.4 * 10^2

expanded form 840

840

Step-by-step explanation:

you need to first multiply 10x10 then when u get the result which is 100 u move the decimal point by the number of zeroes there is in the 100 and u move it two spaces to the right and then just add a zero

the square root of what number? if you add that, then someone will probably answer the question.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
