Solve 5^2+2^2-2*5*cospi/3*0

$$5 ^ { 2 } + 2 ^ { 2 } - 2 \times 5 \times \cos \frac { \pi } { 3 } \times 0$$

Evaluate

$$19$$

Solution Steps

Calculate 5 to the power of 2 and get 25.

$$25+2^{2}-2\times 5\cos(\frac{\pi }{3}\times 0)$$

Calculate 2 to the power of 2 and get 4.

$$25+4-2\times 5\cos(\frac{\pi }{3}\times 0)$$

Add 25 and 4 to get 29.

$$29-2\times 5\cos(\frac{\pi }{3}\times 0)$$

Multiply 2 and 5 to get 10.

$$29-10\cos(\frac{\pi }{3}\times 0)$$

Anything times zero gives zero.

$$29-10\cos(0)$$

Get the value of \cos(0) from trigonometric values table.

$$29-10\times 1$$

Multiply 10 and 1 to get 10.

$$29-10$$

Subtract 10 from 29 to get 19.

$$19$$
