Answer:

91

Step-by-step explanation:

We just have to put in the value of x into the equation.

  8 - 4[x - (2x² + 5)] + 3

= 8 - 4[3 - (2×3² + 5)] + 3

= 8 - 4[3 - (2×9 + 5)] + 3

= 8 - 4[3 - (18 + 5)] + 3

= 8 - 4(3 -23) + 3

= 8 - 4(-20) + 3

= 8 - (-80) + 3

= 8 + 80 + 3

= 91

Use the product property of roots to choose the expression equivalent to 3√5x*3√25x^2?
nignag [31]

Answer: \sqrt[3]{125x^3}.


Step-by-step explanation: Given radical expression

\sqrt[3]{5x} \times \sqrt[3]{25x^2}.

According to the product property of roots.

\sqrt[n]{a} \times \sqrt[n]{b} = \sqrt[n]{a \times b}

On applying above rule, we get

\sqrt[3]{5x} \times \sqrt[3]{25x^2} = \sqrt[3]{5x \times 25x^2}

5 × 25 = 125 and

x \times x^2 = x^3

Therefore,

\sqrt[3]{5x \times 25x^2}= \sqrt[3]{125x^3}

<h3>So, the correct option would be second option \sqrt[3]{125x^3}.</h3>
