Answer 3

can you check this please?


1) 8x10^4

= 80000.

2) 9.82x10^5

= 98,200,000.

3) 9x10^-3

= 0.0009

4) 7.24x10^-6

= 0.00000724

Answer 4

#1 is correct.

The power of 10 refers to the number of positions the decimal point has to be moved, <i>not</i> the number of zeroes.
So for #2, it should be
9.82000*100000=982000
Similarly, for #3,
9x10^3=9/1000=0.009
I will leave #4 for you to try.
