Which expression is equivalent to StartFraction (5 a b) cubed Over 30 a Superscript negative 6 Baseline b Superscript negative 7 Baseline EndFraction? Assume a not-equals 0, b not-equals 0.

StartFraction a Superscript 7 Baseline b Superscript 10 Baseline Over 6 EndFraction

StartFraction 125 a Superscript 18 Baseline b Superscript 21 Baseline Over 30 EndFraction

StartFraction 25 a cubed b Superscript 4 Baseline Over 6 EndFraction

StartFraction 25 a Superscript 9 Baseline b Superscript 10 Baseline Over 6 EndFraction

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
