Solve V=sqrt{left(4*10^7right)^2}+left(3*10^7right)^2

$$V = \sqrt{ { \left(4 \times { 10 }^{ 7 } \right) }^{ 2 } } + { \left(3 \times { 10 }^{ 7 } \right) }^{ 2 }$$

Solve for V

$$V=900000040000000$$

Steps for Solving Linear Equation

Calculate 10 to the power of 7 and get 10000000.

$$V=\sqrt{\left(4\times 10000000\right)^{2}}+\left(3\times 10^{7}\right)^{2}$$

Multiply 4 and 10000000 to get 40000000.

$$V=\sqrt{40000000^{2}}+\left(3\times 10^{7}\right)^{2}$$

Calculate 40000000 to the power of 2 and get 1600000000000000.

$$V=\sqrt{1600000000000000}+\left(3\times 10^{7}\right)^{2}$$

Calculate the square root of 1600000000000000 and get 40000000.

$$V=40000000+\left(3\times 10^{7}\right)^{2}$$

Calculate 10 to the power of 7 and get 10000000.

$$V=40000000+\left(3\times 10000000\right)^{2}$$

Multiply 3 and 10000000 to get 30000000.

$$V=40000000+30000000^{2}$$

Calculate 30000000 to the power of 2 and get 900000000000000.

$$V=40000000+900000000000000$$

Add 40000000 and 900000000000000 to get 900000040000000.

$$V=900000040000000$$

Assign V

$$V≔900000040000000$$
