when multiplying a number to a power, you add the powers.
for example 5^3 x 5^8 = 5^11
you can do the same with 2&9, 4&7, 5&6
Answer:
Step-by-step explanation:
x = 100
The area of the left square is 3600
A =s^2
3600 = s^2
Taking the square root of each side
60 =s
The area of the right square is 1600
1600 = s^2
40 =s
Adding the lengths
60+40 =x
100 =x
