Apply the properties of integer exponents to generate equivalent expressions to 4⁰ • 5^-²/(-2)^-³ with only positive exponents, then solve the expression. Your answer will be a simplified fraction with no remaining exponents.

4⁰ • 5^-²/(-2)^-³ =

3 answers

To apply the properties of integer exponents, we can use the following rules:

1. Any number raised to the power of 0 is always 1: a^0 = 1, where a is any real number.
2. A negative exponent can be converted to a positive exponent by taking the reciprocal of the base: a^(-n) = 1/a^n, where a is any nonzero real number and n is a positive integer.

Using these rules, we can rewrite the given expression:

4⁰ • 5^-²/(-2)^-³
= 1 • (1/5²)/(1/(-2)³) (Using rule 1 and rule 2)
= 1 • (1/25)/(1/(-8))
= 1 • (-8/25) (Simplifying the fractions)

Therefore, the equivalent expression in positive exponents is 1 • (-8/25) = -8/25.

I apologize for the mistake. Let's try again:

To apply the properties of integer exponents and generate equivalent expressions with only positive exponents, we can use the following rules:

1. Any number raised to the power of 0 is always 1: a^0 = 1, where a is any nonzero real number.
2. A negative exponent can be converted to a positive exponent by taking the reciprocal of the base: a^(-n) = 1/a^n, where a is any nonzero real number and n is a positive integer.
3. When multiplying two numbers with the same base raised to different exponents, we can add the exponents: a^n * a^m = a^(n+m), where a is any nonzero real number and n, m are integers.

Let's apply these rules to the given expression:

4^0 • 5^(-2) / (-2)^(-3)

Using rule 1, we know that 4^0 is equal to 1:

1 • 5^(-2) / (-2)^(-3)

Now, let's apply rule 2 and convert the negative exponents to positive exponents:

1 • 1/5^2 / 1/(-2)^3

Simplifying the denominator, we have:

1 • 1/5^2 / 1/(-8)

Calculating the values of the exponent:

1 • 1/25 / 1/(-8)

Using rule 3, we know that dividing by a fraction is the same as multiplying by its reciprocal. So we can rewrite the expression as:

1 • 1/25 * (-8/1)

Simplifying the fractions:

1/25 * (-8)

Multiplying the numerator:

-8/25

Therefore, the equivalent expression with only positive exponents is -8/25.
