Question

Solve the two questions :-

Answer 1

Answer:

solution to the problem is given above

Answer 2

Answer:

(I) 37/16

(2)9/4

Step-by-step explanation:

(1) {(1/4)^-3-(1/3)^-3}÷(1/4)^-2

To solve the first bracket we have to positive the power of each term and if we change the sign of powe then the term will be reciprocal like the terms will be changed and power will be positive

{(4/1)^3-(3/1)^3}÷(4/1)^2

{(4/1×4/1×4/1)-(3/1×3/1×3/1)}÷(4/1×4/1)

{(64/1-27/1)}÷(16/1)

(64-27)×(1/16)

=37×1/16

=37/16

(2) (2/3)^-6×(3/2)^-4

(3/2)^6×(2/3)^4

(3/2×3/2×3/2×3/2×3/2×3/2×2/3×2/3×2/3×2/3

now here there will be cutting and by cutting we will get

3/2×3/2

=9/4
