Solve (9*10^9)*1*-10/4.5div10^9

$$\frac{ (9 \times { 10 }^{ 9 } ) \times 1 \times -10 }{ 4.5 } \div { 10 }^{ 9 }$$

Evaluate

$$-20$$

Solution Steps

Calculate 10 to the power of 9 and get 1000000000.

$$\frac{\frac{9\times 1000000000\times 1\left(-10\right)}{4.5}}{10^{9}}$$

Multiply 9 and 1000000000 to get 9000000000.

$$\frac{\frac{9000000000\times 1\left(-10\right)}{4.5}}{10^{9}}$$

Multiply 9000000000 and 1 to get 9000000000.

$$\frac{\frac{9000000000\left(-10\right)}{4.5}}{10^{9}}$$

Multiply 9000000000 and -10 to get -90000000000.

$$\frac{\frac{-90000000000}{4.5}}{10^{9}}$$

Expand \frac{-90000000000}{4.5} by multiplying both numerator and the denominator by 10.

$$\frac{\frac{-900000000000}{45}}{10^{9}}$$

Divide -900000000000 by 45 to get -20000000000.

$$\frac{-20000000000}{10^{9}}$$

Calculate 10 to the power of 9 and get 1000000000.

$$\frac{-20000000000}{1000000000}$$

Divide -20000000000 by 1000000000 to get -20.
