Solve 4*3.14*3.14*1.2*10^9*1.2*10^9*10^9*1.2

$$4 \times 3.14 \times 3.14 \times 1.2 \times { 10 }^{ 9 } \times 1.2 \times { 10 }^{ 9 } \times { 10 }^{ 9 } \times 1.2$$

Evaluate

$$68149555200000000000000000000$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 9 and 9 to get 18.

$$4\times 3.14\times 3.14\times 1.2\times 10^{18}\times 1.2\times 10^{9}\times 1.2$$

To multiply powers of the same base, add their exponents. Add 18 and 9 to get 27.

$$4\times 3.14\times 3.14\times 1.2\times 10^{27}\times 1.2\times 1.2$$

Multiply 4 and 3.14 to get 12.56.

$$12.56\times 3.14\times 1.2\times 10^{27}\times 1.2\times 1.2$$

Multiply 12.56 and 3.14 to get 39.4384.

$$39.4384\times 1.2\times 10^{27}\times 1.2\times 1.2$$

Multiply 39.4384 and 1.2 to get 47.32608.

$$47.32608\times 10^{27}\times 1.2\times 1.2$$

Calculate 10 to the power of 27 and get 1000000000000000000000000000.

$$47.32608\times 1000000000000000000000000000\times 1.2\times 1.2$$

Multiply 47.32608 and 1000000000000000000000000000 to get 47326080000000000000000000000.

$$47326080000000000000000000000\times 1.2\times 1.2$$

Multiply 47326080000000000000000000000 and 1.2 to get 56791296000000000000000000000.

$$56791296000000000000000000000\times 1.2$$

Multiply 56791296000000000000000000000 and 1.2 to get 68149555200000000000000000000.

$$68149555200000000000000000000$$
