Question

Insert the corresponding expression:

$\left(\frac{1\times5}{4\times6}\right)^{-2}=$

00:00 Simply

00:03 According to the laws of exponents, any fraction raised to power (N)

00:09 equals the numerator and denominator raised to the same power (N)

00:13 We will use this formula in our exercise

00:19 We will raise both numerator and denominator to power (N)

00:32 This is one solution to the question

00:36 According to the laws of exponents when the entire product is raised to power (N)

00:40 equals each factor in the product separately raised to the same power (N)

00:44 We will use this formula in our exercise

00:57 And this is the solution to the question

a' + b' are correct
