Question

calculați: 2⁷:4³+3³×27:3⁵+(3¹×2⁴-4²):2³​

Answer 1

2⁷:4³+3³×27:3⁵+(3¹×2⁴-4²):2³=

2⁷:(2²)³+27×27:3⁵+(3×16-16):8

2⁷:2⁶+27²:3⁵+32:8

2¹+(3³)²:3⁵+4

2+3⁶:3⁵+4

2+3+4=9

Answer 2

2⁷:4³+3³×27:3⁵+(3¹×2⁴-4²):2³ =

$= 2 ^{7} \div {2}^{6} + {3}^{3} \times {3}^{3} \div {3}^{5} + (3 \times {2}^{4} - {2}^{4}) \div {2}^{3}$

$= 2 + 3 + {2}^{5} \div {2}^{3}$

$= 2 + 3 + {2}^{2}$

$= 2 + 2 + 4$

$= 9$
