Solve 7^4+47^3+47^2

$${ 7 }^{ 4 } +4 { 7 }^{ 3 } +4 { 7 }^{ 2 }$$

Evaluate

$$3969$$

Solution Steps

Calculate 7 to the power of 4 and get 2401.

$$2401+4\times 7^{3}+4\times 7^{2}$$

Calculate 7 to the power of 3 and get 343.

$$2401+4\times 343+4\times 7^{2}$$

Multiply 4 and 343 to get 1372.

$$2401+1372+4\times 7^{2}$$

Add 2401 and 1372 to get 3773.

$$3773+4\times 7^{2}$$

Calculate 7 to the power of 2 and get 49.

$$3773+4\times 49$$

Multiply 4 and 49 to get 196.

$$3773+196$$

Add 3773 and 196 to get 3969.

$$3969$$

Factor

$$3^{4}\times 7^{2}$$
