Math problem: You are enlarging a photo on your computer screen. The photo starts at 3 centimeters wide. Each time you enlarge the photo, its width is doubled. You enlarge the photo four times. What is the final width of the photo on your screen?

Answer 1

ans: 81 cm

work:

since the photo starts at 3 cm wide and the width gets doubled each time for four times, youd have to do 3^4.

in other words,
3 x 3 x 3 x 3

3x1 is 3,
3x3 is 9,
9x3 is 27,
27x3 is 81

Answer 2

48 centimetres wide

Explanation:

you are at 3

you enlarge it and you get 6

second enlargement you get 12

third enlargement you get 24

fourth enlargement you get 48

if you times 3 by 4 you are not doubling the width each time you enlarge the photo

so it is easier to double it each time you enlarge it
