Solve 3sqrt{49}-4sqrt[3]{-125}+sqrt{4,84}

$$3 \sqrt { 49 } - 4 \sqrt[ 3 ] { - 125 } + \sqrt { 4,84 }$$

Evaluate

$$43,2$$

Solution Steps

Calculate the square root of 49 and get 7.

$$3\times 7-4\sqrt[3]{-125}+\sqrt{4,84}$$

Multiply 3 and 7 to get 21.

$$21-4\sqrt[3]{-125}+\sqrt{4,84}$$

Calculate \sqrt[3]{-125} and get -5.

$$21-4\left(-5\right)+\sqrt{4,84}$$

Multiply -4 and -5 to get 20.

$$21+20+\sqrt{4,84}$$

Add 21 and 20 to get 41.

$$41+\sqrt{4,84}$$

Calculate the square root of 4,84 and get 2,2.

$$41+2,2$$

Add 41 and 2,2 to get 43,2.

$$43,2$$

Factor

$$\frac{2 ^ {3} \cdot 3 ^ {3}}{5} = 43\frac{1}{5} = 43.2$$
