Video Solution

Solution Steps

00:00 Simplify the following problem
00:03 According to the laws of exponents, a fraction raised to a power (N)
00:07 equals the numerator and denominator raised to the same power (N)
00:11 We will apply this formula to our exercise
00:15 This is the solution

Step-by-Step Solution

To solve this problem, we need to simplify the expression (15)3 \left(\frac{1}{5}\right)^3 using the exponent rules for fractions:

  • Step 1: Identify the base and the exponent. Here, the base is 15 \frac{1}{5} and the exponent is 3 3 .
  • Step 2: Apply the rule for raising a fraction to a power. The rule states that (ab)n=anbn \left(\frac{a}{b}\right)^n = \frac{a^n}{b^n} .
  • Step 3: Apply the exponent to both the numerator and the denominator:

Thus, (15)3=1353 \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} .

Therefore, the simplified expression is 1353 \frac{1^3}{5^3} , which corresponds to choice 1 in the provided options.

Answer

1353 \frac{1^3}{5^3}
