Solve (-1/2*10^3)*(4*10^7)

$$(- \frac{ 1 }{ 2 } \times { 10 }^{ 3 } ) \times (4 \times { 10 }^{ 7 } )$$

Evaluate

$$-20000000000$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 3 and 7 to get 10.

$$-\frac{1}{2}\times 10^{10}\times 4$$

Calculate 10 to the power of 10 and get 10000000000.

$$-\frac{1}{2}\times 10000000000\times 4$$

Express -\frac{1}{2}\times 10000000000 as a single fraction.

$$\frac{-10000000000}{2}\times 4$$

Divide -10000000000 by 2 to get -5000000000.

$$-5000000000\times 4$$

Multiply -5000000000 and 4 to get -20000000000.

$$-20000000000$$

Factor

$$-20000000000$$
