nomor 1
100^8 x 100^5 ÷ 100^3 x 100^8 ÷ 100^5 x 100^3 ÷ 100^5
100^(8 + 5 - 3 + 8 - 5 + 3 - 5)
100^11
nomor 2
nilai A
2a + 8 = 24
2a = 24 - 8
2a = 16
a = 16/2
a = 8
nilai b
2b - 3 + 5 = 8
2b = 8 + 3 - 5
2b = 11 - 5
2b = 6
b = 6/2
b = 3
nilai c
2c + 7 - 3 = 14
2c = 14 - 7 + 3
2c = 7 + 3
2c = 10
c = 10/2
c = 5
A
a x b + c - a x b - c ÷ c
8 x 3 + 5 - 8 x 3 - 5 ÷ 5
120 - 24 - 1
95
B
a x b x c + c - b + a - c
8 x 3 x 5 + 5 - 3 + 8 - 5
120 + 2 + 3
125
nomor 3
volume
p x l x t
8 x 3 x 5
24 x 5
120 cm³
luas permukaan
2( pl + pt + lt)
2(8(3) + 8(5) + 3(5))
2(24 + 40 + 15)
2(79)
158 cm²
semoga membantu dan mohon dikoreksi
Jawaban:
Nomor 1
100⁸ × 100⁵ ÷ 100³ × 100⁸ ÷ 100⁵ × 100³ ÷ 100⁵
100⁸+⁵-³+⁸-⁵+³-⁵
100¹¹
Nomor 2
2a + 8 = 24
2a = 24 - 8
2a = 16
a = 16/2
a = 8
2b - 3 + 5 = 8
2b - 3 = 8 - 5
2b - 3 = 3
2b = 3 + 3
2b = 6
b = 6/2
b = 3
2c + 7 - 3 = 14
2c + 7 = 14 + 3
2c + 7 = 17
2c = 17 - 7
2c = 10
c = 10/2
c = 5
A = 8 × 3 × 5 - 8 × 3 - 5 ÷ 5
A = 120 - 24 - 1
A = 95
B = 8 × 3 × 5 + 5 - 3 + 8 - 5
B = 120 + 2 + 3
B = 122 + 3
B = 125
Nomor 3
Lp = 2 × (p × l) + (p × t) + (l × t)
Lp = 2 × (8 × 3) + (8 × 5) + (3 × 5)
Lp = 2 × (24 + 40 + 15)
Lp = 2 × 79
Lp = 158 cm²
Volume = p × l × t
Volume = 8 × 3 × 5
Volume = 120 cm³
