Question

Which shows the expression below in simplified form?

(4.5 × 10^10) + (4 × 10^9)

Answer 1

are you allowed to use a calculator for this problem ?

Answer 2

yes

Answer 3

these numbers are using a special notation instead of writing a bunch of zeroes all the time
so 4 x 10^9 is the same as 4000000000

Answer 4

u need this app called yhomework it works

Answer 5

you need to know how to enter numbers in your calculator in this notation - it's called scientific notation I think

Answer 6

yeah that's what the name of the quiz is :/

Answer 7

or you could try to get your head round it, it's not that hard
4.5x10^10 would be 4500000000
4x10^9 is 4000000000
you could just add them up on paper

Answer 8

it's not asking me to solve the expression , it's asking me to simplify it ..

Answer 9

well what they mean I think is just add up the numbers and write the answer in scientific notation, that's all

Answer 10

there's not any more simplifying you can do with it

Answer 11

can you see that this addition comes to 49000000000 ?

Answer 12

i don't see what more you can do with it
