Answer: -50

This equation is asking you to multiply 50 by -1. When a number is in parentheses alone next to another number, the equation is usually asking for multiplication.

When a number is multiplied one, the value of the number remains the same. Since this is -1, however, the value will become -50.

Answer:

Step 1, all the exponents are increased by 4

Step-by-step explanation:

The three steps are

(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ =
x²×y⁸/y⁴×x⁸×x⁸×y² =
x²×y⁸/y⁶×x¹⁶

Correct solution should be:

(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = all powers inside the parenthesis should be multiplied by 4 as per power of the power (xᵃ)ᵇ = xᵃᵇ

This would give next steps:

x⁻⁸×y¹⁶/y⁴×x⁸×x⁸×y⁻⁸ =
x⁻⁸×y¹⁶/x¹⁶×y⁻⁴ =
y²⁰/x²⁴

Answer options:

Step 1, all the exponents are increased by 4

There should be multiplication of powers. (It is close option but is not fully correct as not all the exponents increased by 4, for example y became y⁴)

Step 2, the exponents of the same base are added during multiplication
