Soal Nomor 8
L = ½( a¹ + a² )t
L = ½( 10√2 + √72 )( 3√6 )
L = ½( 10√2 + 6√2 )( 3√6 )
L = ½( 16√2 )( 3√6 )
L = ( 8√2 )( 3√6 )
L = 24√(4×3)
L = (24×2)√3
L = 48√3 cm²
Soal Nomor 9
0,000000000101 = 1,01 × 10-⁹
Soal Nomor 10
( 8,8 × 10⁶ ) - ( 3,5 × 10⁵ )
= 8.800.000 - 350.000
= 8.500.000 - 50.000
= 8.450.000
= ( 8,45 × 10⁶ ) kg
