Video Solution

Solution Steps

00:00 Simplify the following problem
00:04 According to the laws of exponents, any fraction raised to the negative exponent (-N)
00:08 equals the reciprocal fraction with the same exponent (N) multiplied by (-1)
00:15 We will apply this formula to our exercise
00:22 This is the solution

Step-by-Step Solution

To solve the problem, apply the negative exponent rule:

  • For any fraction ab\frac{a}{b} with a negative exponent n-n, apply the rule: (ab)n=(ba)n\left(\frac{a}{b}\right)^{-n} = \left(\frac{b}{a}\right)^{n}.

Apply this rule to the given expression (1013)2\left(\frac{10}{13}\right)^{-2}:

(1013)2=(1310)2 \left(\frac{10}{13}\right)^{-2} = \left(\frac{13}{10}\right)^{2}

Therefore, the correct expression with a positive exponent is (1310)2\left(\frac{13}{10}\right)^{2}.

In the provided choices, this is option:

  • (1310)2 \left(\frac{13}{10}\right)^2

Hence, the correct expression is (1310)2\left(\frac{13}{10}\right)^2.

Answer

(1310)2 \left(\frac{13}{10}\right)^2
