Question

pls solve b, C, d question

Answer 1

Step-by-step explanation:

b){(⅓)^-3 -(½)^-3}+(¼)^-3

={(⅓-½)^-3}+(¼)^-3

=LCM of 3 and 2 is 6

=(2-3/6)^-3+(¼)^-3

=(-1/6)^-3+(¼)^-3

=LCM of 6 and 4 is 12

=(-2+3/12)^3

=(-1/12)^3

c){(4/-3)^-3}²

=(4/-3)^-3×2

=(4/-3)^-6

d)(3^-1+4^-1)^-1+5^-1

=(7^-1+5^-1)

=12^-1

=1/12
