15x10^2 + 5.2x10^5 can you awnser this

521,500 or 5.215 x 10^5

Step-by-step explanation:

A quick way to solve something that is multiplied by 10^n, simply move the decimal point the same number as n. (For example, 1.6 x 10^3 simply move the decimal to the right 3 times 1600.0)

Therefore,

15 x 10^2 = 1500

5.2 x 10^5 = 520000

1500 + 520000 = 521500 or 5.215 x 10^5

521,500

Step-by-step explanation:

(15*(10^2)+(5.2*(10^))

1,500+520,000

521,500
