Question

Difficulty: EasyOperations with Variable Exponents

Pair each basic algebraic expression with its correctly simplified result by applying the fundamental laws of exponents.

  • m6⋅m2m^6 \cdot m^2m8m^8
  • n8n5\frac{n^8}{n^5}n3n^3
  • (p4)3(p^4)^3p12p^{12}
  • q−5q^{-5}1q5\frac{1}{q^5}

Answer

The correct pairings are: m6⋅m2m^6 \cdot m^2 with m8m^8; n8n5\frac{n^8}{n^5} with n3n^3; (p4)3(p^4)^3 with p12p^{12}; and q−5q^{-5} with 1q5\frac{1}{q^5}.
Each expression can be simplified by directly applying one specific fundamental property of exponents. m6⋅m2m^6 \cdot m^2 uses the product rule. n8n5\frac{n^8}{n^5} uses the quotient rule. (p4)3(p^4)^3 uses the power rule. q−5q^{-5} uses the negative exponent definition.

Step-by-Step Solution

1
Simplify the product expression m6⋅m2m^6 \cdot m^2.
m8m^8
When bases are identical and multiplied, their exponents are added together.
2
Simplify the quotient expression n8n5\frac{n^8}{n^5}.
n3n^3
When dividing identical bases, the exponent of the denominator is subtracted from the exponent of the numerator.
3
Simplify the nested power expression (p4)3(p^4)^3.
p12p^{12}
When raising an exponent to another power, the two exponents are multiplied.
4
Rewrite the negative exponent expression q−5q^{-5}.
1q5\frac{1}{q^5}
A negative exponent indicates taking the reciprocal of the base raised to the positive exponent.
