Question

simplify (b)4^-3 x 6^-5
2^-5 x 3^-6 x 9^-4​

Answer 1

Step-by-step explanation:

4^-3 × 6^-5 × 2^-5 × 3^-6 × 9^-4

= 1/4³ × (1/6⁵ × 1/2⁵) × 1/3⁶ × 1/9⁴

using identity a^x × b^x = (ab)^x

1/4³ × 1/12⁵ × 1/3⁶ × 1/9⁴

OR

now solving

1/64 × 1/248832 × 1/729 × 1/6561

WHICH IS 64^-1 × 248832^-1 × 729^-1 × 6561^-1
