Question

$(( {5}^{ - 1} \times {3}^{ - 1} ) {}^{ - 1} \div {6}^{ - 1} )$
step by step method pls​

Answer 1

Answer:

90

See the attachment for answer.

Answer 2

(5^-1 * 3^-1)^-1 ÷ 6^-1

= [(5*3)^-1]^-1 ÷ 6^-1

(aⁿ * bⁿ = (ab)ⁿ)

= (15^-1)^-1 ÷ 6^-1

[(a^m)ⁿ = a^m*n]

= 15^(-1*-1) ÷ 6^-1

= 15¹ ÷ 6^-1

[a^-n = 1/aⁿ]

= 15 ÷ 1/6¹

= 90
