Question

Evaluate (4/7)-⁵ × (7/3)-³ ×(4/3)⁷​

Answer 1

Answer:

9 and (55/81)

Step-by-step explanation:

I assume the assignment is

$(4/7)^{-5}$ × $(7/3)^{-3}$ × $(4/3)^{7}$ =

$(7/4)^{5}$ × $(3/7)^{3}$ × $(4/3)^{7}$ = ($7^{5}$ × $3^{3}$ × $4^{7}$) ÷ ($4^{5}$ × $7^{3}$ × $3^{7}$) =

$7^{5-3}$ × $4^{7-5}$ × $3^{3-7}$ = 7² × 4²× $3^{-4}$ = (49×16) / $3^{4}$ =

784 / 81 = 9$\frac{55}{81}$
