Which could be the first step and simplifying this expression? Check all that apply.
Triss [41]

\bf \left( x^3x^{-6} \right)^2\implies \left( x^{3-6} \right)^2\implies \stackrel{1st~Step}{\left( x^{-3} \right)^2}\implies x^{-6}\implies \cfrac{1}{x^6}\\ \qquad \Downarrow\\ \stackrel{\textit{distributing the exponent}}{\left( x^{3\cdot 2}x^{-6\cdot 2} \right)}\\ \qquad \Downarrow\\ \stackrel{1st~Step}{x^6x^{-12}}\\ \qquad \Downarrow\\ x^{6-12}\\ \qquad \Downarrow\\ x^{-6}\\ \qquad \Downarrow\\ \cfrac{1}{x^6}

EXPLAIN What is the quotient when 1,000,000,000 is divided by 28x 57
Rama09 [41]

Answer:

626,566.42

Step-by-step explanation:

The quotient is answer of a value divided by another value. In this problem we have a value of 1,000,000,000 divided by the product of 28 x 57.

This can be represented like this:

Total=\dfrac{1,000,000,000}{28*57}

Total=\dfrac{1,000,000,000}{1,596}

Total=626,566.42

The fraction can also be used to indicate a number being divided by another number.
