Answer: Student X and Y

Step-by-step explanation:

Student W started off correctly as they simplified the first expression and got rid of the parentheses.

Student Z also started off correctly as they simplified the second expression and combined the like terms.

I don’t see what students X and Y did as their first step but I hope this helps. Sorry if it doesn’t

What is the simplified expression for 4 to the power of negative 3 multiplied by 3 to the power of 4 multiplied by 4 to the powe

Cloud [144]

Answer:

4/3

Step-by-step explanation:

You can simplify the exponent expression using exponent rules. The rules are:

A positive exponent is the number of times the base multiplies by itself.
A negative exponent is the number of times the base divides itself.
Multiplying same bases with exponents is simplified by adding the exponents.
Dividing same bases with exponents is simplified by subtracting the exponents.
A zero exponent always evaluates as 1.

The expression $\frac{4^{-3}3^44^2}{3^54^{-2}}$ can be simplified first using the negative exponent rule to move base with negative exponent to the other part of the fraction.

$\frac{4^{-3}3^44^2}{3^54^{-2}} = \frac{4^{2}3^44^2}{3^54^{3}}$

Now use the multiplication rule to simplify numerator and denominator.

$\frac{4^{2}3^44^2}{3^54^{3}} = \frac{4^{2+2}3^4}{3^54^{3}} = \frac{4^{4}3^4}{3^54^{3}}$

Finally, use the division rule to reduce the fraction.

$\frac{4^{4}3^4}{3^54^{3}}= 4^{4-3} 3^{4-5} = 4*3^{-1} = \frac{4}{3}$
