Best ResponseYou've already chosen the best response.1first multiply 21 * 6.3 and write it in the exponent form post you answer here

Best ResponseYou've already chosen the best response.1can you write that in 'exponent form ? like 1.56 * 10^2

Best ResponseYou've already chosen the best response.1that is one way to write it can you write it as 1.323 * 10^?

Best ResponseYou've already chosen the best response.1no  it is possible can you do it  what is the value of ? so that 132.3 is the same as 1.323 *10^?

Best ResponseYou've already chosen the best response.0I know that you have to move the decimal over two spaces to the left by dividing it by 100. That IS correct, right? XD

Best ResponseYou've already chosen the best response.1yes 132.3= 1.323*100 = 1.323 *10^? what is the value of ? in the above?

Best ResponseYou've already chosen the best response.0I have no clue. 1.323*100 is 132.3 but that's what we started with...

Best ResponseYou've already chosen the best response.1the point of the exercise is to be able to express numbers in exponent form (or sometimes called scientific notation) you can see maybe that (for example) 1101 = 110.1 *10^1 1101 = 11.01 * 10^2 1101 = 1.101 * 10^3 1101 = .1101 * 10 ^4 SO using the same idea can you look at 132.3= 1.323*100 = 1.323 *10^?

Best ResponseYou've already chosen the best response.1132.3= 1.323*100 we are multiplying by 100 how would you write 100 = 10^?

Best ResponseYou've already chosen the best response.1Well I'm afaid you are probably not ready to tackle questions like this then. The key point is that we can move the decimal point where we want  as LONG AS we multiply by 10^? to compensate. BUT you must know that 10^0 =1 10^1 = 10 10^2 = 100 10^3 = 1000 etc.

Best ResponseYou've already chosen the best response.1how would you write 100 = 10^?

Best ResponseYou've already chosen the best response.1OK so lets go back toi the original question 21 *6.3 • 10^4 you worked out was the same as 132.3 *10^4 which is the same as 1.323 *10^2 * 10^4 so what happens when you multiply 2 numbers with exponents? 10^2 * 10^4 = 10 ^?

Best ResponseYou've already chosen the best response.0When you multiply 2 numbers with exponents dont you add the exponents and if the bases are the same then you keep them as that number? So this would be 10^2?
