Question

(3^2 x 4^-3 )(3^2 x 4^3) simplify the following​

Answer 1

3 + 2[4x – (4 + 3x)] = –1

3 + 2[4x – 1(4 + 3x)] = –1

3 + 2[4x – 1(4) – 1(3x)] = –1

3 + 2[4x – 4 – 3x] = –1

3 + 2[1x – 4] = –1

3 + 2[1x] + 2[–4] = –1

3 + 2x – 8 = –1

2x + 3 – 8 = –1

2x – 5 = –1

2x – 5 + 5 = –1 + 5

2x = 4

x = 2

Answer 2

Answer:

81

Step-by-step explanation:

(3² x 4-³ )(3² x 4³)

=(9 x 1/4³)(9x64). (a-ⁿ=1/aⁿ}

= 9 x 1/64 x 64 x 9

= 9x1x9
