Solve (-0,7)^2+(0,2)^3-(-0,8)^2/0,49+0,008-0,64

$$\frac { ( - 0,7 ) ^ { 2 } + ( 0,2 ) ^ { 3 } - ( - 0,8 ) ^ { 2 } } { 0,49 + 0,008 - 0,64 }$$

Evaluate

$$1$$

Solution Steps

Calculate -0,7 to the power of 2 and get 0,49.

$$\frac{0,49+0,2^{3}-\left(-0,8\right)^{2}}{0,49+0,008-0,64}$$

Calculate 0,2 to the power of 3 and get 0,008.

$$\frac{0,49+0,008-\left(-0,8\right)^{2}}{0,49+0,008-0,64}$$

Add 0,49 and 0,008 to get 0,498.

$$\frac{0,498-\left(-0,8\right)^{2}}{0,49+0,008-0,64}$$

Calculate -0,8 to the power of 2 and get 0,64.

$$\frac{0,498-0,64}{0,49+0,008-0,64}$$

Subtract 0,64 from 0,498 to get -0,142.

$$\frac{-0,142}{0,49+0,008-0,64}$$

Add 0,49 and 0,008 to get 0,498.

$$\frac{-0,142}{0,498-0,64}$$

Subtract 0,64 from 0,498 to get -0,142.

$$\frac{-0,142}{-0,142}$$

Divide -0,142 by -0,142 to get 1.

$$1$$
