6,3 + ( -3,7 ) + 2,4 + ( -0,3 )
= ( 6,3 + 2,4 ) + [( -3,7 ) + ( -0,3 )]
= 8,7 - 4
= 4,7
6,3+(-3,7)+2,4+(-0,3)
=(6,3+2,4)+[(-3,7)+(-0,3)]
=8,7+(-4)
=8,7-4
=4,7
6,3 + (-3,7) + 2,4 + (-0,3)
= (6,3 + 2,4) + [(-3,7) + (-0,3)]
= 8,7 + [-(3,7+0,3)]
= 8,7+(-4)
= 4,7
\(=\dfrac{3^5}{-\left(0.003\right)^3\cdot0.09}=-10^{11}\)
\(6,3+\left(-3,7\right)+2,4+\left(-0,3\right)\)
\(=\left[6,3+2,4\right]+\left[\left(-3,7\right)+\left(-0,3\right)\right]\)
\(=8,7+-4\)
\(=4,7\)
\(=\dfrac{\left(0.125\cdot2.4\right)^5}{\left(-0.3\cdot0.01\right)^3\cdot\left(-0.3\right)^2}=\dfrac{0.3^5}{0.3^2\cdot\left(-0.003\right)^3}=\dfrac{0.3^3}{-0.003^3}=-1000000\)
\(6.3+\left(-3.7\right)+2.4+\left(-0.3\right)\)
\(=\left(6.3-0.3\right)-\left(3.7-2.4\right)\)
\(=6-1.3=-4.7\)
\(2.9+3.7+\left(-4.2\right)+\left(-2.9\right)+4.2\)
\(=\left(2.9-2.9\right)+3.7+\left(4.2-4.2\right)\)
\(=3.7\)
a,32
b,\(-\frac{1}{10}\)
c,-1000000
d,\(\frac{9}{16}\)
\(=\dfrac{\left(0.125\cdot2.4\right)^5}{\left(-0.3\right)^3\cdot\left(0.01\right)^3\cdot\left(-0.3\right)^2}=-\dfrac{\left(0.3\right)^5}{\left(0.3\right)^5\cdot\left(0.01\right)^3}\)
\(=-\dfrac{1}{\left(0.01\right)^3}=-\dfrac{1}{\dfrac{1}{1000000}}=-1000000\)
\(6,3+\left(-3,7\right)+2,4+\left(-0,3\right)=\left[6,3+2,4\right]+\left[\left(-3,7\right)+\left(-0,3\right)\right]=8,7+\left(-4\right)=8,7-4=4,7\)
\(6,3+\left(-3,7\right)+2,4+\left(-0,3\right)=\left(6,3+2,4\right)+\left[\left(-3,7\right)+\left(-0,3\right)\right]=8,7+\left(-4\right)=4,7\)
