Question

b^12×(-b)^6= b^18 , please explain it ​

Answer 1

Answer:

a=21b=18

We have a−(−b)

⇒a=21−(−18)=39

and a+b=21+18=39

(ii) a=118b=125

We have a−(−b)

⇒18−(−125)=243

and a+b=118+125=243

Hence proved a−(−b)=a+b

Answer 2

Answer:

b^12×(-b)^6 = b^18

• using formula

a^m ×a^n = a^m+n

= b^12 × -b^6 = b^12+6

• = b^18

hence, LHS= RHS
