tolong jawab yang benar ya kakk...​

Answer 1

Jawaban dengan langkah-langkah:

A. 5,6 * 10^6 - 5 * 10^5 + 4 * 5 * 10^4

= (56 * 10^5) - (5 * 10^5) + (20 * 10^4)

= 5.600.000 - 500.000 + 200.000

= 5.300.000 atau 53 * 10^5

B. (2/5)^2 + (2/5)^(-2)

= (4/25) + (1/4/25)

= 4/25 + 25/4

= (16 + 625)/100

= 641/100

C. (-5)^3 + (-2)^5 + (1/2)^(-4)

= -125 - 32 + (1/1/16)

= -157 + 16

= -141

KET : ^ = pangkat

         * = kali
