Solve 1*2^0+1*2^2+1*2^4

$$1 \times { 2 }^{ 0 } +1 \times { 2 }^{ 2 } +1 \times { 2 }^{ 4 }$$

Evaluate

$$21$$

Solution Steps

Calculate 2 to the power of 0 and get 1.

$$1\times 1+1\times 2^{2}+1\times 2^{4}$$

Multiply 1 and 1 to get 1.

$$1+1\times 2^{2}+1\times 2^{4}$$

Calculate 2 to the power of 2 and get 4.

$$1+1\times 4+1\times 2^{4}$$

Multiply 1 and 4 to get 4.

$$1+4+1\times 2^{4}$$

Add 1 and 4 to get 5.

$$5+1\times 2^{4}$$

Calculate 2 to the power of 4 and get 16.

$$5+1\times 16$$

Multiply 1 and 16 to get 16.

$$5+16$$

Add 5 and 16 to get 21.

$$21$$

Factor

$$3\times 7$$
