simplify-4(2)^2+(5^3)/5

simplify

- 4 (2)^{2} + \frac{5 ^{3}}{5}

9

Solution steps

- 4 \cdot 2^{2} + \frac{5 ^{3}}{5}

- 4 \cdot 2^{2} = - 16

- 4 \cdot 2^{2}

2^{2} = 4

= - 4 \cdot 4

Multiply the numbers:

- 4 \cdot 4 = - 16

= - 16

\frac{5 ^{3}}{5} = 25

\frac{5 ^{3}}{5}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

= 5^{3 - 1}

Subtract the numbers:

3 - 1 = 2

= 5^{2}

5^{2} = 25

= 25

= - 16 + 25

25 - 16 = 9

- 16 + 25
