Tolong jawab kak besok di kumpulin​

Jawab:

1. 2 x 5 x 7

2. 2^{2} x 5^{2}

3. a. 50

   b. 300

4. a. 5

   b. 8

5. a. KPK = 75

       FPB = 5

   b. KPK = 150

       FPB = 10

Penjelasan dengan langkah-langkah:

1. 2 x 5 x 7

2. 2^{2} x 5^{2}

3. a. 25 = 5^{2}

       50 = 2 x 5^{2}

       KPK = 2 x 5^{2} = 2 x 25 = 50

   b. 60 = 2^{2} x 3 x 5

       75 = 3 x 5^{2}

       KPK = 2^{2} x 3 x 5^{2} = 4 x 3 x 25 = 4 x 75 = 300

4. a. 20 = 2^{2} x 5

       45 = 3^{2} x 5

       FPB = 5

   b. 24 = 2^{3} x 3

       40 = 2^{3} x 5

       FPB = 2^{3} = 2 x2 x 2 = 8

5. a. 15 = 3 x 5

       25 = 5^{2}

       FPB = 5

       KPK = 3 x 5^{2} = 3 x 25 = 75

   b. 30 = 2 x 3 x 5

       50 = 2 x 5^{2}

       FPB = 2 x 5 = 10

       KPK = 2 x 3 x 5^{2} = 2 x 3 x 25 = 2 x 75 = 150
